MSN: crash when receiving multipart chat

[wwp]

Hi,

using CVS 2005-03-10 (ICQ, MSN, qt-gui), licq crashed apparently after I received some messages from 3 people coming up in a chat session. Since I was away, I cannot exactly tell when licq did crash, but when I re-started it, I had pending messages from 3 MSN contacts who did initiate a chat (2 w/ MSN, 1 w/ aMSN).

Here is the bt and bt full:

This got fixed when I changed the code to add new users in the multi-user chat to the Not In List. Otherwise, we have no ICQUser pointer and strange shit will happen!

This is fixed in the latest CVS version of Licq. It will be included in the next release, or you may use the CVS version. Read http://www.licq.org/daily.php
