Yes.

Yes. Complete output:

* gnus-agent-expire((8673) "incoming" force)
  gnus-request-move-article(8673 "incoming" "mailse01.axis.se" (gnus-request-accept-article "INBOX" (quote nil) t t) t)
  gnus-summary-move-article(nil)
* call-interactively(gnus-summary-move-article)

Once again, I end up in the debugger. I hit 'c' again.

No. The contents of the message buffer (after having exited
and re-entered the "incoming" group says):

Moving to INBOX: (8673)...

Yup:

$ cvs status gnus-agent.el
===================================================================
File: gnus-agent.el     Status: Up-to-date

   Working revision:    6.142
   Repository revision: 6.142   /usr/local/cvsroot/gnus/lisp/gnus-agent.el,v
   Sticky Tag:          (none)
   Sticky Date:         (none)
   Sticky Options:      (none)

Before doing the steps above I disabled all spam
functionality, exited emacs, downloaded a fresh gnus from
CVS, built it, installed it and then started emacs.
