Comment 12 for bug 354272

Could you remove pidgin-facebookchat and pidgin-musictracker, and redo the profile again? May as well purge since they don't store their own settings.

sudo apt-get remove --purge pidgin-facebookchat pidgin-musictracker

If this fixes the issue, then add only pidgin-facebookchat and try that out. I have a hunch the issue may be in one of these packages. I'm guessing it's most likely in pidgin-musictracker.
