Comment 9 for bug 545751

I'm having the same problem with MSN and Facebook (gmail, yahoo, and another xmpp account are all working fine)..and it also seemed to start soon after upgrading to 10.4. So far, I've tried completely removing empathy and reinstalling it.

I see this in the mission-control debug logs when trying to connect to my msn account....

Message: Failed to get item from keyring: No matching results
Message: Falling back to looking in the keyfile
....this is repeated twice.....
