Debugging x86-Qtopia App

skip2816
Hi,

has any body an idea how I can debug an App written for Qtopia 2.2? 
I tryed kdbg qpe or ddd qpe. Both debuggers fails with "cannot connect to X
server" My error happens very random and possible deep in qt. Logging does
not help.
I have an QMainWindow with any QLabels inside. In a resize event the font
size for the labels is set to fill the whole space with text. While
resizing the App can crash.


thanks
