Comment 1 Eike Hein 2010-06-06 15:26:10 UTC 
Could you give us more info about what organising the server list means - were you dragging networks around in the list, or did you have dialogs to edit a network or a server open?
Comment 2 daviesc95 2010-06-06 20:48:05 UTC 
I was dragging the servers around in the server list (File -> Server List...) When I had finished and closed the server list, and koversation crashed a few seconds later.
Comment 3 Eike Hein 2010-06-06 20:51:51 UTC 
Thanks, that's good info - we're looking into it.
Comment 4 Myriam Schweingruber 2013-04-14 00:54:51 UTC 
Is this still reproducible with Konversation 1.4 or 1.5 RC1? Then we would need
a new backtrace.
