[Interest] Application using qt 5.0 beta 2 crashes

[Sam Van Gucht]

Hi,

I have compiled qt 5 beta 2 on ubuntu 11.04 and want to use it instead 
of the alpha version I'm using now in my application.

But my application crashes when I create a QApplication. It crashes in 
the function QXcbConnection::xi2SetupTabletDevices, when the function 
XIQueryDevice is called.

Did anyone have the same problem or knows a solution?
