XMPP getting "Not Authorized" when joining an P/W protected, already open chat room

标签：situation   criteria   password   network   specific   

When a XMPP password protected room is already set up in a window, and the account is logged back in, Pidgin tries to log into the room without a password and fails with a "Not Authorized" error. Double-clicking on the room in the Buddy List will log into the room properly.

This bug seems to crop up on a specific set of criteria, but given that the situation happens often (at least for me), it is still annoying. I hiberate my laptop often and go on VPN, so it comes up every time the network is re-connected.

Steps to Reproduce (100% reproducible on my side):

1. Log into password-protected XMPP chat room.
2. Keep room window open.
3. Disable account or disconnect Internet connection
4. Enable account or re-connect Internet connection
5. Error occurs when Pidgin attempts to relog into room.

Note the difference between the two presence requests. The first one does not send out a password via XML, and the second one does (which was the manual double-click into the room). So, Pidgin is clearly not sending the password out when it should.
