Application: kopete (1.0.80)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.2
Operating System: Linux 2.6.37-ARCH i686
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I was talking to a MXit contact using the plugin obtainable at http://kde-apps.org/content/show.php/kopete-mxit?content=120176 when Kopete crashed. 

- Unusual behavior I noticed:
Screen turned black. This usually happens when Plasma crashes, although I was not notified of Plasma crashing this time. 

- Custom settings of the application:
I am using a third-party plugin to add MXit support to Kopete.

The crash can be reproduced every time.

-- Backtrace:
Application: Kopete (kopete), signal: Segmentation fault
