Description gt6 2010-02-23 07:34:19 EET

Reproduce:
Do this on an n900 or in scratchbox preferably:
1. Download this sample app: http://stuff.moritzg.ch/dialogcrash.py
2. When running it, hit "remove" and a warning dialog will pop up
3. Close the dialog
4. Repeat Steps 2 and 3 one to five times
5. Segfault

Comments:
- Someone on #pyside confirmed the problem with this sample file
- PyQt doesn't crash with this same code

Comment 1 gt6 2010-03-08 09:12:19 EET

I made a better, shorter test case of this:
http://stuff.moritzg.ch/dialogcrash2.py

It's really short and very clear. Commenting the two lines which set a Layout
on the Dialog stops it from segfaulting. Like this, a couple of tries segfault
it.
PyQt does not segfault with the same script, although in my app, which is
bigger and has more stuff in the dialogs, PyQt also crashes, but seemingly less
frequently. The segfault occurs when the dialog is opened, starting from the
3rd opening upwards.

I tried some times with pyside-shiboken from git HEAD, on desktop, and it
didn't crashed.

Need to test if this bug still valid.
