"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.
Details
In this particular case, for the reference, I was more-or-less following instructions on http://arstechnica.co.uk/security/2015/10/how-to-use-tor-messenger-the-most-secure-chat-program-around/. After creating a Jabber account on the jabber.calyxinstitute.org 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!arstechnica.com@my.onsip.com.
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.
