Qt version 3.3.6 has got problems with -fstack-protector of gcc-3.4. I have noticed this issue on AMD64, but perhaps it affects other architectures as well. Earlier versions worked fine. The exact error looks as follows: $ someqtapp someqtapp: stack smashing attack in function void QPainter::setWorldMatrix(const QWMatrix&, bool)() Aborted It is triggered by an attempt to draw a window, so sometimes it is possible to actually launch a Qt app (e.g. one can start Psi when its docking mode is enabled and it's configured not to show the roster window by default). Not that it helps much, considering this is a GUI library... Let me know if you need any more information.
