            Bug ID: 319137
           Summary: Crash in DialogShadows::Private::freeX11Pixmaps()
    Classification: Unclassified
           Product: kdelibs
           Version: unspecified
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: kded
          Assignee: unassigned-bugs at kde.org
          Reporter: christoph at maxiom.de

Application: kded4 (4.10.60)
KDE Platform Version: 4.10.60 (Compiled from sources)
Qt Version: 4.8.4
Operating System: Linux 3.8.9-1-desktop i686
Distribution: "openSUSE 12.2 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:

After recent change in master, I got this crash when exiting kded4. I guess the
X connection has already been closed when the global static exit handlers are
called.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
