            Bug ID: 323274
           Summary: Display configuration crashes when changing resolution
    Classification: Unclassified
           Product: systemsettings
           Version: 4.10.5
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: bugzilla at wintonian.net

Application: kcmshell4 (4.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.5
Operating System: Linux 3.10.4-300.fc19.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

I had changed the resolution in Catalyst (13.8 beta) to 1600x900 and sometime
later proceeded to changed the resolution in in "display configuration" also to
1600x900 (forgetting what resolution I was currently running) and on clicking
"apply" the crash happens.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Control Module (kcmshell4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
