Comment (by smcv):

 Activities on the server and link-local activities are distinct. We know
 that, and there's nothing we can do about it in the short or medium term.

 However...

 The way the PS is *meant* to be working (I fixed a related bug this
 morning) is that activities on the server are advertised to the server,
 and activities that are link-local are advertised on the local link - i.e.
 if you can see someone's activity, you can join it.

 It's possible that this bug is caused by activities not being unadvertised
 when they should be, or by activities being advertised on the wrong
 protocol.

 In either case, we may have fixed it "accidentally" with the refactoring
 we did for invitation support - in order to make invitations sane, we
 tightened some restrictions, so attempting to advertise an activity that
 doesn't actually exist (on this protocol) will fail, and activities will
 be unadvertised automatically when they cease to exist. If the Presence
 Service is buggy, Gabble will raise an error instead of accepting the
 wrong information, and we'll see tracebacks in the PS log.
