Comment 7 for bug 450184

I reported it upstream to Gnome, who marked it as Invalid and forwarded me onto freedesktop.org's mailing list (3 different bug trackers... yay!)

I had some messaged from Sjoerd there:
"I read through the bugreport, but it doesn't seem like a clear cause has been
identified. From our side of the fence this is quite hard to debug (as in, it's
hard to guess what behaviour in Gabble would trigger this issue without knowing
openfire)."

The telepathy-gabble list @ freedesktop is the correct place although without knowing how to help them get the data they need, I cannot submit the bug.
