Possible fix

As I am unable to reproduce or do not know how to reproduce, can someone who is able to reproduce please try the attached patch?

The crash seems to happen since Qt 4.6 (all duplicates are from Qt 4.6.0) in QPixmap::handle(). Looking at the source code ( http://qt.gitorious.org/qt/qt/blobs/d16ba0a93d611689bce9a2732a1cc8c9a317f5bf/src/gui/image/qpixmap.cpp#line1168 ) I can't see anything possible wrong. So my only idea is that the pixmap is a null pixmap and testing for that should hopefully prevent the crash.
Comment 9 Martin Flöser 2010-01-01 12:57:08 UTC 
SVN commit 1068519 by graesslin:

Only load the decoration texture if the decoration pixmap is not null.
This resulted in a crash with Qt 4.6 when accessing the pixmap handle.

Comment 10 Martin Flöser 2010-01-01 12:59:16 UTC 
After discussion on IRC I committed the patch. Christoph could you please try if it is really fixed?
Comment 11 Christoph Feck 2010-01-01 13:10:12 UTC 
I only got the crash once. But I can confirm that Qt 4.6 crashes when calling handle() on a null pixmap, while Qt 4.5 does not, so adding this check can only help. I will reopen if I see it after your commit.
