Bug 257821

Application: knode (4.4.6)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-23-generic x86_64
Distribution: Ubuntu 10.10

-- 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
