[maemo-developers] N950 SEGFAULT - help?

[From: Felipe Crochik]

Nicolai,

I tried the application using (I assume that is what you meant):
QApplication::setGraphicsSystem("opengl");

and haven't been able to crash the application but it gets really slow and
unresponsive. Also I get these error messages on my log:

Valid eglHandle received but not running with meego compatible
graphicssystem.

Any ideas?

Thanks,
Felipe
