            Bug ID: 343677
           Summary: KDE setting crashes when I click Hardware -> Power
                    management -> Advanced setting
           Product: systemsettings
           Version: unspecified
          Platform: Mint (Ubuntu based)
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: johnjohnlys at gmail.com

Application: systemsettings (4.11.11)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.13.0-37-generic x86_64
Distribution: Linux Mint 17.1 Rebecca

-- Information about the crash:
- Custom settings of the application:
The configuration is inherited from Mint 17 and I just installed 17.1
yesterday.
I think it's OK because all of the other settings work fine.
However as long as I click "Hardware -> Power management -> Advanced setting",
it crashes.

The crash can be reproduced every time.
