crash1.txt (shiboken.dll)

I've got a reproducible crash when closing single window component. The code is
available under 'pyside-100beta1-crash' from
http://code.google.com/r/techtonik-styledtextedit/source/browse?r=pyside-100beta1-crash

Attached are Vista crash logs. Although two first are different, the 3rd and
4th runs produced matching data.

Comment 4 Matti Airas 2010-12-15 10:34:50 EET

Thanks for the bug report. Unfortunately, I found this a bit difficult to work
with. Could you provide us a bit more specific test case which exhibits the
crash and the commands required to clone the hg repo (at least I'm have no
prior experience with hg and couldn't clone the given URL with "hg clone").

I'm keeping this unconfirmed for now.

I am attaching non-minimal example that crashes. Don't really have time to
minimize it right now. The problem seems to be in autocomplete mechanism.

This version without line numbers still crashes.

Comment 7 Matti Airas 2010-12-15 12:19:06 EET

OK, I can reproduce on Linux. Since this is a crasher bug, I'm prioritizing
this P2. Thanks!

Removed properties/options. Still crashes on exit.

Ok. Here is the minimal example. The problem is in
self.completer.setWidget(self) code.

This'll help solving the issue a lot.
