It's calling the nntp function instead of the nnimap function, so I'm
guessing that the Gnus async function(s) just haven't been fixed to
rely on other backends than nntp.

*read code*

Yes, that seem to be the case.  (That's odd.  I really thought that
the async stuff should work for all backends.  Do I misremember
totally?  Am I misreading the code?  I have a suspicion that there's
something I'm not remembering...)

If that is, indeed, the case, then the following patch is the right
one.  :-/
