Description johnjohnlys 2015-02-02 06:14:59 UTC 
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.

-- Backtrace:
Application: 系統設定 (systemsettings), signal: Segmentation fault

Comment 1 Albert Astals Cid 2015-09-26 10:57:13 UTC 
I can't reproduce this using a modern Plasma 5 system.

I know this bug is old but do you remember if you could reproduce it every time or was a one off crash? 

Can you still reproduce it?
Comment 2 johnjohnlys 2015-09-30 06:32:01 UTC 
Yes, the KDE System Setting always crashes as long as I click "Hardware -> Power management -> Advanced setting".
However I have no such problem on another computer with Linux Mint 17.2.
So I'm not sure whether this is a hardware related bug or is just owing to wrong configuration.
Comment 3 Albert Astals Cid 2015-10-01 19:36:10 UTC 
Can you please try running system settings under valgrind

valgrind systemsettings

And attach here the backtrace of the crash when run under valgrind?
