Description Benjamin Kleiner 2009-12-05 11:04:08 UTC 
Application that crashed: kopete
Version of the application: 0.80.2
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.6.0
Operating System: Linux 2.6.31-15-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I had set up a Bonjour/iChat network at home, with Avahi+Kopete on Linux and Bonjour+PidginPortable on Windows. Kopete doesn't seem to see any of the other network members, but they see it, so message sending only works from Windows to Linux. However, whenever I send a message from there, Kopete simply crashes.

Comment 1 Tejas Dinkar 2009-12-07 06:25:59 UTC 
I will look into why you cannot receive messages.

It is possible that you cannot see any contacts because your firewall is preventing avahi broadcasting.

You will need to open 5353/UDP in your firewall.

Please paste the output of "avahi-browse -at" here.

Comment 3 Benjamin Kleiner 2009-12-09 20:29:46 UTC 
Problem solved "itself". Yes, my firewall had all necessary ports open. It was the fact my notebook is hooked to two subnets: one for the whole family, except my Desktop Computer, and one between my notebook and said PC. Whenever 192.168.0.0 is down, I can see everyone, both in Kopete and avahi-browse.

However, the crash remains, but now it occurs as soon as the opposite site leaves the chat. Also happens between two instances of kopete, but only on one site (the one that hadn't left).

Added a second backtrace of one of those instances, though it looks almost the same as the first one.
Comment 4 Roman Jarosz 2010-02-07 15:18:06 UTC 
The crash in Comment #2 is fixed (will be in KDE SC 4.4.1), the first backtrace is different
