[PyQt] segfault : interpreting back trace

[Erik Janssens]

Hi,

I'm having a pyqt segmentation fault, and I cannot find out what is
causing it.  Can somebody make some suggestions on how to handle this ?

I tried to use gdb to get a back trace, but it doesn't make much sense
to me, it seems to be related to a c-function call, but I don't know
which one (back trace below)

Any help or suggestion is appreciated.

regards,

Erik
