    \title Known Issues

    This section lists known issues in \QC version \qtcversion. The development
    team is aware of them, and therefore, you do not need to report them as
    bugs.

    For a list of fixed issues and added features, see the changelog file in
    the \c{qtcreator\dist} folder or the \l{https://bugreports.qt.nokia.com}
    {Qt Bug Tracker}.

    \section1 General Issues

    \list

        \o  If you change the Input Languages in Windows, \QC might not
            respond for 30 seconds. This is a known issue in the Advanced Text
            Service of Microsoft Windows.

        \o  \QC uses SQLite for storing some of its settings. SQLite is
            known to have problems with certain NFS servers (most notably the
            nfs-user-server 2.2beta), since they can lock up the application
            when it tries to lock the database. If your home directory is on an
            NFS share and you encounter this issue, one option would be to
            switch to the nfs-kernel-server, or create a symlink so that the
            settings are stored locally.

        \o  The Okteta KDE custom widget plugin might be installed as part of
            some Linux distributions. It can cause Qt Designer to crash. For
            more information, see:

            \list

                \o  \l{https://bugs.launchpad.net/ubuntu/+source/kdeutils/+bug/662005}
                    {Ubuntu bug 662005}

                \o  \l{https://bugreports.qt.nokia.com/browse/QTBUG-12025}
                    {QTBUG-12025}

           \endlist

            To resolve the issue, enter the following command to remove the
            package:
            \code
            sudo apt-get remove okteta
            \endcode
            Or delete the following file:
            \c /usr/lib/kde4/plugins/designer/oktetadesignerplugin.so.

    \endlist

    \section1 Editing Issues

    \list

        \o Code completion does not support typedefs for nested classes.

    \endlist

    \section1 Projects Issues

    \list

        \o  Paths or file names containing spaces or special characters
            (such as colons, dollar signs, and hash marks) may cause problems.
            This is because some of the tools \QC uses in the background have
            restrictions on the characters allowed in file and directory names.
            To be on the safe side, we recommend creating projects and project
            items with names consisting of plain characters, numbers,
            underscores, and hyphens.

        \o  Creating new CMake projects with \QC is not supported.

        \if defined(qcmanual)
        \o  On Windows, you must create projects for Maemo 5 and Harmattan
            targets on the same partition where you installed \QSDK, \QC, and
            MADDE.
        \endif

        \o  If error messages displayed in the \gui {Compile Output} pane contain
            paths where slashes are missing (for example, C:QtSDK),
            check your PATH variable. For more information, see
            \l{Troubleshooting MinGW Compilation Errors}.

    \endlist

    \section1 Debugging Issues

    \list

        \o  Debugging large applications on Symbian devices using the Symbian^3
            operating system might not work, because the on-device debugging
            agent might not be able to access memory when the operating system
            starts paging. This causes breakpoint handling and symbol resolution
            to fail. For more information, see
            \l{https://bugreports.qt.nokia.com/browse/QTCREATORBUG-2158}
            {QTCREATORBUG-2158}.

            As a workaround, add the following section to the application .pro
            file to disable paging:

            \code
            debug {
                MMP_RULES -= PAGED
                MMP_RULES *= UNPAGED
            }
            \endcode

            \note You must completely clean and rebuild the project for the
            setting to take effect.

        \o  When debugging executables created by the GNU Compiler version 4.5.0
            (all platforms), some data types will not be displayed in the
            \gui{Locals and Expressions} view due to missing debug information.

        \o  GDB on Windows may not work if the 'Embassy \reg Security Center'
            software by 'Wave \reg Systems' is installed and active (causing
            crashes in \c{vxvault.dll)}).

        \o  GDB may take long to load debugging symbols, especially from large
            libraries.

        \o  Setting breakpoints in code that is compiled into the binary more
            than once does not work.

        \o  Setting breakpoints in files that do not have unique absolute
            paths may fail. For example, remounting parts of a file system
            using the --bind mount option.

        \o  A regression in GCC 4.5.0 causes return value optimization to
            produce inaccurate debug info that GCC applies also to
            non-optimized builds. For more information, see
            \l{http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44731}
            {GCC Bugzilla – Bug 44731}.

    \section1 Qt Quick Designer Issues

    \list

        \o  \QMLD uses external processes (QML Puppet) to render and preview
            images and to collect data. Executing C++ code might cause the QML
            Puppet to crash. If it crashes, an error message is displayed and
            you can continue editing the QML file in the code editor.
