Bug 288978

Application: systemsettings (1.0)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
I opened System Settings and clicked on Network Settings.  It does this repeatedly - rebooting doesn't cure it.  Sometimes, going into and out of SSL settings without changing anything stops the crash.  Once it stops crashing, it won't crash again - so perhaps the bug is an uninitialized variable somewhere.

The crash can be reproduced every time.

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