+I wrote a test program to try to connect to this server, using a test account, and dump some events. This works on linux. Then I tried it on mac, and I think I have reproduced the same failure!
+
+<pre>
+oberon:~ joeyh$ ./xmpp
+xmpp: <socket: 3>: hGetBuf: resource vanished (Connection reset by peer)
+</pre>
+
+Note that this exception is unable to be caught, it seems. Which would explain why the whole git-annex assistant crashes.
+
+Also, the same program, when modified to use some other xmpp server, does not crash.
+
+At this point, I think I need to forward this bug to network-protocol-xmpp author John Millikin. Which I've now done.
+
+My advice for the bug submitter: git-annex is going to be deprecating XMPP in the not too distant future anyway. If you have your own server, a much nicer way to use git-annex is to install it on the server and use ssh remotes. Recent versions do not need xmpp to sync between clients in such a configuration.
