           Summary: kded crash
           Product: kdelibs
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: kded
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: nick at leverton.org


Application: kded4 ($Id$)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic-pae i686
Distribution: Ubuntu 11.10

-- Information about the crash:
kded crashed spontaneously whilst the machine was unattended.  May have been
related to a drop of the wireless connection but I don't know as I wasn't
there.

I had been browsing and playing music.  I left the stream on for someone else
to listen to but am not sure if it was still going at the time of the crash.

-- Backtrace:
