crashes here immediately on startup. Attached the backtrace.
It's a fresh Qt5 build on a virtual machine.
Ubuntu 12.04 based distro
gcc 4.6.3
All is fine with Qt4.
I have a debug setup here so I could provide more information.
When I remove fglrx it crashes in libxcb-glx, see attachment.
Is this maybe a bug in the distro/driver and not in Qt?
