Bug 329933

Application: systemsettings (1.0)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.5.0-18-generic i686
Distribution: Ubuntu 12.04.4 LTS

-- Information about the crash:
- What I was doing when the application crashed: There are two occasions where those crashes happen: 1) every time the system starts 2) when you attempt to change the date and time of the system. Consider that my system is not so stable since I have a VIA P4M800 as graphic card, so very poor graphic results (forced xorg.conf to use vesa driver) and a general slowness and high battery consumption. Unluckily, the computer is a Fujitsu-Siemens Amilo L7320, the problems on this hardware is diffused as you can see from the forums on every Ubuntu flavours... Mayne a little bit OT, but ask me if you need more infos (I hope to be able to tell you!!). Regards

The crash can be reproduced every time.
