Package: python2.5
Version: 2.5.2-11.1
Severity: important
I consider segfaulting quite an issue (especially if it happens during simple
warning output), thus raised severity to important. I am not sure if the
original cause is elsewhere (e.g. python-gobject, so I CC its maintainer on
this bugreport), but I guess python's code should be more tollerant, thus
I am complaining about python. I would appreciate if you spot the actual
problem and forward bug-report against corresponding package.
Ways to reproduce (tried on 2 boxes, mostly lenny):
there is a young project dataview3d, which you can get from
https://www.ynic.york.ac.uk/~andre/DV3D_downloads/source/DV3D_v0.35C_dist.zip
(you might like to fix up permissions after extraction from evil zip ;-))
just run
python2.5 RunDV3D.py
and don't select any file (cancel) in the dialog which comes up
then it segfaults at

I am not sure why assertion wasn't triggered since tstate is NULL...
in any case -- here is a full backtrace (I rebuilt python-gobject without
optimization and with debuggin info):
