           Summary: KDED4 Daemon crash after resume from sleep
           Product: kdelibs
           Version: unspecified
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: kded
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: tittiatcoke at gmail.com


Application: kded4 ($Id$)
KDE Platform Version: 4.8.00 (4.8.0) "release 48"
Qt Version: 4.8.0
Operating System: Linux 3.2.0-2-desktop x86_64
Distribution: "openSUSE 12.2 Milestone 0 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
When having BlueDevil running, the KDED4 daemon crashes everytime when resuming
from a sleep.  When I remove the BlueDevil daemon through systemsettings, then
the system is resuming normally without a crash. 

I compared the backtrace of bug #284052 and they seem similar, but I do not
have any issue when the system is idle. However I also have the Network
Management Plasmoid active, so it could be related.

The crash can be reproduced every time.
