Comment 4 for bug 848757

I found out the problem, but still I would need to find the very root cause of this issue. It seems that a Jabber MUC I had set as auto-join suddenly started killing the whole connection for yet unknown to me reasons. I missed this lead because I wrongly assumed that settings such as favorite channels are being held alongside account data in .mission-control/. But as they are not, even after reconfiguring the account, auto-join was still enabled and crashed the connection.

It seems trying to join that given MUC kills the connection, which I think still should not happen. But at least I found a work-around my problem. Will try some more regarding this issue.
