Hello Björn, thanks for the bug report. I believe that the "correct" way
to deal with such groups is simply to kill them (C-k in *Group* buffer).

The documenatation says the following about the bogus group:

A group that exists in the ‘.newsrc’ file, but isn’t known to the server
(i.e., it isn’t in the active file), is a _bogus group_.  This means
that the group probably doesn’t exist (any more).

So basically if you remove the select method corresponding to a
particular group then Gnus is not able to check for bogus groups.
