Application: konversation (1.3.1)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
Ubuntu 10.10 i386 32bit fresh install, Konversation 1.3.1 from the original ubuntu rep.
QCA: 2.0.2-1ubuntu2 0

- What I was doing when the application crashed:

I just type /keyx anywhere in chat and it crashes at once.
Tried it on freenode and irc.rbose.org, in private chat, channel window, status window...
also if someone is trying that on me, my konversation client crashes at once too.
(Had same problem with keyx on Konversation 1.2.1. In 1.2.3 it worked fine.)

Reproducable steps: 1. install ubuntu 10.10 i386 32bit final 2. install konversation 1.3.1 from normal rep 3. type in chat somewhere /keyx 4. crash

I hope my bug report helps. :)
If you have questions, email me please.

Greetings and all the best,
DNS

The crash can be reproduced every time.
