Bug 267730

Application: systemsettings (1.0)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-27-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Open systemsettings
First roll down Shortcuts and gestures
Click Global keyboard shortcuts
Then Standard keyboard shortcuts

In this direction, for me, 3-4 times i tried, always crashed. (With other options it isn't.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
