Did you recompile the application after the upgrade? What does the backtrace say?

Yeah, totally clean rebuild. All object files removed, qmake re-run etc

Um... I am not mixing QT4 and QT3 libraries here by mistake am I....?
Well, yes you are using Qt4 libraries: #9 0x00002adf2b62de4b in _init () from /usr/lib64/libQtCore.so.4.
You should be using the libs from /usr/lib/qt3/lib64/.
Make sure LD_LIBRARY_PATH contains /usr/lib/qt3/lib64/ before usr/lib64 and also make sure QTDIR points to the right qt installation.
Regards
It should be enough to rebuild qwt - without uninstalling Qt4.
Seems that you are.
