Bug 310828

Application: kcmshell4 ()
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.5.0-19-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:

I came from rekonq/options/privacy/manage cookies to change the cookie policy for a single site. After changing the policy from reject to accept and clicking OK the module crashed. This crash occurs with every site I pick. No changes were applied.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Control Module (kcmshell4), signal: Segmentation fault
