[Message part 1 (text/plain, inline)]

Dear all,

start of gnus fails, if .newsrc.eld contains a directory group.
Steps to reproduce:

Create empty directory: mkdir /tmp/foo
Start emacs with neither .newsrc nor .newrc.eld nor .nnmail-cache:
src/emacs -Q
Start gnus: M-x gnus ("No news is good news", which is expected.)

Subscribe to /tmp/foo as directory group:
G d /tmp/foo
That group appears.  Hitting space to read messages, I see "Group
nndir:/tmp/foo contains no messages", which is expected.
Quit gnus: q y
Quit emacs.

Now .newsrc exists and is empty, and .newsrc.eld exists and is attached.
Start emacs again:
src/emacs -Q
Starting gnus fails:
M-x gnus
-> Last messages from echo area are (with non-printable characters

nnmail-pathname-coding-system file-name-coding-system
nnmail-file-coding-system nnml-active-file nnml-group-alist
nnmail-find-file nnmail-get-active t] 2], 2

The same scenario also fails with a non-empty directory:
Quit emacs, delete .newsrc and .newsrc.eld.
If I copy an e-mail into /tmp/foo before invoking "G d", I see that
directory as group and can read the e-mail just fine.  After
restarting emacs, "M-x gnus" fails with the above error message.

Output from "M-x report-emacs-bug" follows.

Thanks for the report. It would be great if you could check if it works
in 24.1 and 24.2.

By experiment, no it does not. So, not necessary to fix this for 24.3.

It's due to the back end function nndir-request-list that was
misconfigured, I think.  I've committed the fix in the trunk.
In addition to this, I found two unused[1] backend functions
nndir-request-newsgroups and nndraft-request-newsgroups; removed.
