            Bug ID: 308052
          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: unassigned-bugs at kde.org
           Summary: KDE always crashes
    Classification: Unclassified
                OS: Linux
          Reporter: taysky04 at yahoo.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: kded
           Product: kdelibs

Application: kded4 ($Id$)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-31-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
I reinstalled Ubuntu and now every time I start my computer the KDE crash
handler appears. This doesn't appear to be related to any previous bugs because
the bugs that appeared in the suggested list in the KDE crash handler app
seemed to be totally random.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
