Iain, thanks so much for making this public.  Private master bugs are an
'orrible shackle, hopefully that won't happen, soon.

So, I added glib2.0 and libdbusmenu to the bug, and updated the
description.  It looks like the problem is in one of those, and probably
not in nautilus, which didn't change the day the bug appeared in
quantal.  So it might be most accurate to mark the nautilus component
'Invalid', but I'm afraid that could confuse people and perhaps lead
them to think this is not the bug they're looking for.  So I left that
alone.  Thanks.

  both prominent in the stacktrace.  (I can't tell yet which is really
  the culprit, so, excuse my imprecision, I'm adding them both to the
