            Bug ID: 328260
           Summary: Panel crashed after trying to re-add it.
    Classification: Unclassified
           Product: plasma
           Version: 4.11.3
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: plasma-bugs@kde.org
          Reporter: gustavokrm@gmail.com

Application: plasma-desktop (4.11.3)
KDE Platform Version: 4.11.3
Qt Version: 4.8.5
Operating System: Linux 3.11.9-200.fc19.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I removed the panel because I had experienced some strange behaviours with it,
so I clicked to add a new default panel and the error ocurred. 

- Unusual behavior I noticed:
The battery monitor appears on the top left corner of the screen. Also, I
sometimes am not able to turn off the computer. I am not sure if that's related
though, but this is what led me to remove the panel.

The crash can be reproduced sometimes.
