Still no luck, recompiling with debug symbols gaves following backtrace (all 
examples bundles with qt source also gaves same bt);

Could you please check your qt4/qt4 apps linked against libxcb? Assuming qt4 
has no problem with libxcb, if anyone has another suggestion what may cause 
that problem i really want to hear?

Cheers
