I've tried that with two of my own imap servers, but no luck, everything
works as expected.

Only in my head! It's something I would like to work on, but I haven't
started yet, so that can't be it. I really don't know how my changes
could have caused it.

Does this actually work? I would have thought you had to fully specify
the archive method.

This is obsolete and you might as well delete it.

This variable appears not to exist -- though it sounds both fascinating
and horrifying.

You might as well get rid of this too, as it's no longer used.

The only other thing I can think of is setting `gnus-verbose' to 10 and
showing us all the messages: that will at least tell you a little bit
more about what Gnus thinks it's doing.
