-- Information about the crash:
- What I was doing when the application crashed:KNode crashes when
unsubscribing from newsgroups
This occurred several times whenever I tried to unsubscribe.
It occurred when right clicking and selecting unsubscribing from the menu also
it did the same when using the main menu option. It actually crashes at the
confirmation dialog after pressing the ok button.
The crash can be reproduced every time.
-- Backtrace:
Application: KNode (knode), signal: Segmentation fault
