Version:           0.7.93 (using KDE 3.1.93 (CVS >= 20031111), yes)
Compiler:          gcc version 3.2
OS:          Linux (i686) release 2.4.21-1up.1

1. Start Kopete and sign in.
2. Open chat window with a contact.
3. Turn on the chat members list in the chat window, if it is not already enabled.
4. Left-click your own screen name.

Crash.  Highly reproducible.  I only use AIM, so I don't know if this is reproducible with other protocols.
