Hi,

I've just written a similar test for pure Qt (in C++) and I get a similar crash for \
gnome 3. So it seems that the problem comes from qt/gnome3.

Cheers,
Jan

Hi,

I've checked my Ubuntu 14.04 with

00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated \
Graphics Controller (rev 03)

pyqt 4.10.4 and qt4:4.8.5:

1) for GNOME 3 it crashes as well
2) for GNOME Flashback (Compiz) / (MetaCity) it does not crash but the dialog behaves \
strange 3) for Ubuntu Unity it works fine, i.e. the dialog is shrunk into the monitor \
size.

Additionally for Compiz (after clicking) I get some funny errors, i.e.

jkotan@alcest:~$ python qlabeltest2.py 
QNativeImage: Unable to attach to shared memory segment.

Hi,

for me it crashes also for

    python-pyqt5 (5.3.2+dfsg-3)

on debian/jessie.

I use

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller (rev 09)

(I don't know if it metters).

Bests,
Jan
