Bug 327215

Application: kcmshell4 ()
KDE Platform Version: 4.8.5 (4.8.5) (Compiled from sources)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic i686
Distribution: Linux Mint 13 Maya

-- Information about the crash:
I was changing the time to the correct Australian Daylight Savings time. I pushed the Apply button and the module crashed. I ended up changing the time through the system settings menu to  the correct DST and applied it with  no  module hang.

It has been a while since this netbook was used or powered up. Also thinking back to the startup the track pad did not work. I had to shut down and reboot the system and that fixed it. That is when I tried to change the time and the module went crazy and hung. Changing everything through the system settings menu seems  to of corrected the issue without the module hanging.

The crash can be reproduced some of the time.
