Application: kcmshell4 ()
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.5.0-21-generic i686
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
I was just trying to normally close the setup window, just after putting the flag for changing the time automatically according to the time server.
Then i clicked "apply" and then "ok". Maybe, in that case,  when clicking "ok" it tries to re-do some operations already in progres due to clicking on "apply".
Maybe just checking and eventually avoiding re-doing would be enough.

The crash can be reproduced every time.
