Error while entering an nnimap group

Error while entering an nnimap group

[Nevin Kapur]

I've noticed recently that entering a particular group for the first
time gives the following error.  If hit RET again, I am able to enter
the group just fine.

Signaling: (wrong-type-argument number-char-or-marker-p nil)
  gnus-agent-save-alist("nnimap+fastmail:INBOX" (22) nil)

I just tried to reproduce this, by using `G m' to create a new nnimap
group, then using `C-u a' from the group buffer to post an article
into it, then using `RET' to enter the group.

This did not produce any error.

Do you know what I can do to reproduce the error?  Can you reproduce
it?

If I can't reproduce it, could you investigate where the problem
comes from?  Position point inside the function definition of
gnus-agent-save-alist, then type M-x edebug-defun RET, then reproduce
the error.  You will see that Emacs shows you the function and then
you can use SPC to single-step through it.  What happens when you do
that?

I could, on the day that I posted the message, but today, I can't.
The error only occurred on a particular group.

I will try this the next time the error occurs.
