-The Qt library is the GUI library used by the KDE project. Currently
-there are two versions of the Qt library in use: Qt3 by KDE 3 and Qt4
-by KDE 4. If possible, use Qt4 instead of Qt3. Qt3 is no longer
-supported, and there are known problems with multithreading support in
-Qt3. As an example, using QString objects in more than one thread will
-trigger race reports (this has been confirmed by Trolltech -- see also
-Trolltech task <ulink
-url="http://trolltech.com/developer/task-tracker/index_html">#206152</ulink>).

-Qt4 applications are supported by DRD, but only if the
-<literal>libqt4-debuginfo</literal> package has been installed. Some
-of the synchronization and threading primitives in Qt4 bypass the
-POSIX threads library, and DRD can only intercept these if symbol
-information for the Qt4 library is available. DRD won't tell you if it
-has not been able to load the Qt4 debug information, but a huge number
-of data races will be reported on data protected via
-<literal>QMutex</literal> objects.
