Subject: bug#35233: 27.0.50; Error in gnus-group-describe-all-groups
Date: Thu, 11 Apr 2019 17:54:25 +0100

The recent move to hash-tables[1] introduced the following regression:

0. HOME=$(mktemp -d) emacs -Q
1. (setq gnus-select-method '(nntp "news.gwene.org")) C-j
2. M-x gnus RET s M-d
   Wrong number of arguments: #<subr sort>, 1

Passing string-lessp to sort further leads to the following:

3. Steps 0-2 as above.
   Wrong type argument: vectorp, #s(hash-table ...)

Replacing (intern group gnus-description-hashtb) with just group, and
repeating steps 0-2 as above, reveals that
gnus-group-describe-all-groups inserts the group name twice, rather than
the group name followed by its description.  This regression predates
the move to hash-tables[2].
