            Bug ID: 344472
           Summary: SystemSettings crashes
           Product: systemsettings
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: gahzinia at gmail.com

Application: systemsettings (4.11.15)
KDE Platform Version: 4.14.4
Qt Version: 4.8.6
Operating System: Linux 3.18.6-200.fc21.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I had a keyboard shortcut setup (using launch 3 button to run a custom script).
A few weeks ago, I ran yum update, rebooted, and then shortcut quit working. I
downgraded the updated packages and was then able to reconfigure the shortcut.
A few days ago I ran a yum update again hoping that whatever didn't work had
been fixed. I did not reboot and all things kept working. I installed
FlightGear and have had a few issues with that where 
$ fgfs --show-aircraft 
will core dump. That happened a year or so ago when I was playing Flight Gear
and so that isn't related to the shortcut / yum update / downgrade issues.
However, this time when I tried playing the game, the whole system would hang
for 10 or 20 minutes and eventually out of memory. Well, while impatiently
waiting for it oom or let me do anything (control alt f2-f7 wouldn't even work)
I hit control alt backspace a few times and finally had to hold the power
button. I think that it was after this that the shortcut quit working again. 
I haven't tried to yum downgrade again yet.

The crash can be reproduced sometimes.
