Test program

When use setExpanded(True) on item, and it parent (from item.parent()) test
program ends with segmentation fault, but not in setExpanded() function.
When I use stored item (not from item.parent()) test program works fine.

On PyQt4 always work fine.

I wasn't able to test deeper because of python-dbg problem (bug 506).

PySide was compiled from sources.

OS:
Debian squeeze
Linux 2.6.32-5-686 #1 SMP i686 GNU/Linux

Thanks for the bug report. Since this is a crasher bug, I'm prioritizing it P2.
This will be taken care of once the preceding P2 bugs have been resolved.

Comment 3 Piotr Sokołowski 2010-12-28 07:00:43 EET

Apparently problem isn't fully resolved or there is some other problem, because
after commenting second "self._updateTree()" line in test case file
(tests/QtGui/bug_547.py) test ends with segfault probably when cleanup is
triggered.
