[sip-comm-dev] Multiple simultaneous Jabber errors that I don't understand


I noticed that a Jabber account of mine appeared offline in the global
status menu. It must have disconnected because I remember it being
online before. I clicked its status menu to make it Available but it
didn't succeed and almost immediately displayed two error dialogs. I
don't understand the errors so I'm posting them here in case a problem
with them is found.

One of the dialogs tells me that I've logged more than once with the
same account. But my account is offline?!

The other tells me that it failed to create a Jabber chat room. I
guess it happened because I have a "favorite" chat room to which I
auto-join with this Jabber account and it was triggered some time
after I tried to make the account Available. But it didn't eventually
become available so I'm not sure why is it joining my chat room. "More
info >>" displays the following:

BTW, the text area displayed after clicking "More info >>" is editable
(which I don't think it should be).
