            Bug ID: 324450
           Summary: Remote Control configuration crashes when trying to
                    add new mode
    Classification: Unclassified
           Product: systemsettings
           Version: 4.11.0
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: foss at christian-reiner.info

Application: kcmshell4 (4.11.00)
KDE Platform Version: 4.11.00
Qt Version: 4.8.5
Operating System: Linux 3.7.10-1.16-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
When I try to add a new mode to the existing setup of my remote control (Apple
IR remote, working fine otherwise), the control center module crashes and
produces the attached backtrace. 

The crash is 100% reproduceable. It happens regardless of the dialog being
launched from the control center or from the docklet.

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".
