Trying to save a draft, e.g. as follows:
0. HOME=$(mktemp -d) emacs -Q
1. M-x toggle-debug-on-error RET
2. (setq gnus-select-method '(nnnil)) C-j
3. M-x gnus RET
4. m
5. foo C-x C-s
results in the following error:
--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
nndraft-update-unread-articles()
run-hooks(after-save-hook)

call-interactively(save-buffer nil nil)
command-execute(save-buffer)

Reevaluating nndraft-update-unread-articles and repeating step (5) gives
the following backtrace:

I'm temporarily working around this by
changing (zerop (gnus-group-group-unread))
to (eq 0 (gnus-group-group-unread)),
but a larger problem seems to be at play.
Any tips? Thanks,

Oh, I could 100% reproduce this issue. Maybe the cause of
the failure was I did it in the real home directory instead of
the pseudo home. Probably Gnus loaded something from ~/News .
Sorry.
Me culprit. The cause is that `nndraft-update-unread-articles'
fails to go to the nndraft:queue group (in order to delete the
group line if the group has no unread article). nndraft:queue
and its directory are created when Gnus launches, and it is
registered into `gnus-active-hashtb' but not `gnus-newsrc-hashtb'.
So, `gnus-group-goto-group', that I recently changed so as to
use `gnus-newsrc-hashtb' instead of `gnus-active-hashtb', fails
to find the nndraft:queue group.
I've pushed the fix. Thank you for pointing this out.
Regards,
