"Unknown error" reported by Tor Messenger without further info

Observed behavior: Tor Messenger just gave me an error message saying just "Unknown error".
Expected behavior: for proper usability, all error messages include details or instructions for figuring them out. In this case, I'm guessing Tor Messenger should tell me that I can't start a private conversation without first being accepted by the other user (if that's the problem), but I don't know.

I probably did not use Tor Messenger as I should, and I have a very limited understanding of OTR, but I still should get a better error — the current one is unsuitable even for a programmer like me.


In this particular case, for the reference, I was more-or-less following instructions on
After creating a Jabber account on the server, I added the author of that article (as he suggests to readers!), and he didn't authorize me yet (and might as well be offline). I opened a conversation with him, and got

12:49:45 - The current conversation is not private.

Meanwhile, two new errors/warnings appeared in the Error Console (see below).
Then, I pressed "Start private conversation" with his contact, and I got these new messages, but no new error on the Error Console.

12:49:49 - Attempting to start a private conversation with cyrus.farivar!
12:49:49 - Unknown error

Looking at the first exception shows an uncaught exception during requestRoomInfo; so probably the later error happens because the connection-state is not in a state where I can start a private conversation. Consistently with this hypothesis, my "Known fingerprints" window shows no entry.

For the record: this worked easily when he got back online — so the main problem is just with the error handling.

Thanks for reporting. Indeed, the error message is unhelpful. It comes from,

The stanza we're returned is,

<message xmlns="jabber:client" id="..." type="error" to="" from="">
 <error xmlns="jabber:client" type="cancel">
  <service-unavailable xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/>

The only condition Instantbird provides a useful message for is "remote-server-not-found".

I'll add this case and maybe others from,
