Evaluating this in the (Message mode) reply buffer, evaluating the above
gives "sent.2012-09".  Evaluating `gnus-message-archive-method' gives
"archive".  Looking through the `gnus-group-prefixed-name' function, I
see that this happens because

(gnus-server-to-method "archive")

returns nil.  Perhaps because some part of Gnus has not been
initialized?  (I did not run M-x gnus before using debbug-gnus.)

Am I to understand that you can't reproduce this?  It is 100%
reproducible for me.
