I did nothing more than unsubscribed from a group.  After restarting knode I again attempted to unsubscribe to another group, which also resulted in a crash.

[Comment from a bug triager]
From bug 256226:
I had 6 subscribed groups (on
Giganews.com) and every time I go to remove one I get an 'are you sure?' dialog
box, which I confirm and then Knode (or Kontact, depending on which one I'm
using) crashes. On a restart, the group has been unsubscribed.

from bug 281816

I was unsubscribing from a newsgroup in knode as descibed in bug #248256.
According to bug #248256, this or a very similar crash has been fixed in kdepim
4.4.10, however I just got it in 4.4.11.
