Bug 307507

Application: konversation (1.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-30-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was connected to geekshed irc (not tested on any other networks). Entering /unban #channel where channel can be any random channel where you are banned or not, will crash konversation. Tried it repeatedly always with the same result.

The crash can be reproduced every time.

-- Backtrace:
Application: Konversation (konversation), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
