           Summary: Crash changing icon size of side bar in kontact
           Product: kontact
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: fire at projectstarfire.de

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

Changing the size of the icons of the side bar. The backtrace is very different
to the one I marked as a possible duplicate. Maybe this is a different bug?

The crash can be reproduced some of the time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
