Bug 193312

May be related to r968537 or r967957 ? If this turns out to be a KPixmapCache bug, please reassign to kdelibs.

This may be related to those revisions or it may not, but it definitely seems like an issue in KPixmapCache. Reassigning to kdelibs.

Robert, could you compile with debugging in KDE and Qt enabled, and provide a backtrace with debugging information?

Unfortunately, the kde binary packages I'm using (from Mark Constable) don't have debugging symbols enabled.  I can rebuild from source, but there's no guarantee I will be able to reproduce the bug if I'm building things in a different way.  I will try anyway.

I've been having issues with my development environment (I'd been using VirtualBox to keep from messing up my production KDE4).  I've decided to simply install to a user account instead (which should help) and will then be able to provide a backtrace (I hope).  Probably today or tomorrow....

Is no one else seeing this issue?

Backtrace with debugging information

I recompiled with debugging information.  Here's the backtrace.  It looks to me like it's crashing in a different spot, though....

Robert, the backtrace in comment #5 is indeed a different issue, either a Qt bug or a bug in KPatience.

Paste of the attachment from comment #5 to help finding the right duplicate:

I can no longer reproduce this, so I'm going to assume it's fixed.  Thanks!
