            Bug ID: 303722
          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: unassigned-bugs at kde.org
           Summary: KDE daemon crashes randomly.
    Classification: Unclassified
                OS: Linux
          Reporter: sundance at ierne.eu.org
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: kded
           Product: kdelibs

Application: kded4 ($Id$)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-26-generic-pae i686
Distribution: Ubuntu 12.04 LTS

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

Nothing whatsoever. It's a work computer which stays on at night. This morning
I found the crash dialog waiting for me and decided it was time I reported the
issue.

This happens regularly, perhaps once every few weeks or so.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Aborted
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
