           Version: 4.11.1
          Platform: openSUSE RPMs
                OS: Linux

          Severity: crash
          Priority: NOR
         Component: kded
          Assignee: unassigned-bugs at kde.org

Application: kded4 (4.11.1)
KDE Platform Version: 4.11.1

Operating System: Linux 3.11.0-1-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I have just updated to KDE 4.11.1. At every start, kde daemon crashes. I
removed libkscreen libkscreen1 kscreen packages and it is OK now.

The crash can be reproduced every time.
