Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:

* Is this reproducible?
* If so, what specific steps should we take to recreate this bug?

This will help us to find and resolve the problem.

i have the same problem. it is happening with the latest version of the facebookchat-plugin (1.37). sometimes it happens when you launch pidgin, sometimes later, during a conversation. notifications are turned off, so it can't be that...

unfortunately, this happens stochastically, so i can't define a fixed way to reproduce this...

[Dimitrios Symeonidis (azimout)]

note that the plugin is here:
http://code.google.com/p/pidgin-facebookchat/
it's not supported by ubuntu (but maybe we could put it in multiverse?)

[Dimitrios Symeonidis (azimout)]

this is with pidgin 2.5.1 on intrepid beta

[Dimitrios Symeonidis (azimout)]

please note that, with the facebook account disabled, pidgin never crashes, so this is almost definitely related to the pidgin-facebookchat plugin

also note that many of the related issues i mentioned above seem to indicate that this might be caused by the plugin handling incorrectly facebook chat being down for maintenance at times...

i can confirm this under Ubuntu 8.10 x86 without facebook plugin also of pidgin 2.5.2

Is this still an issue in more recent release of pidgin/purple?
