davmail and nnimap issues

[Steinar Bang <sb@dod.no>]

When the current gnus HEAD, nnimap with davmail is back to this
behaviour:
 http://permalink.gmane.org/gmane.emacs.gnus.general/83746

In short: the correct number of unread articles is reported, but when I
enter the group, this single line is all that I see in the summary
buffer:
 O  [   ?: nobody                 ] (none)
(the text colour of the line is blue)

Before entering the summary buffer of the group and displaying the above
results, it reads a lot of data, ie. lines like this in the minibuffer.
 nnimap read 900k from localhost

It also write these two lines to the minibuffer:
 No more unseen articles
 No more unread articles

Looking at the IMAP traffic between gnus and davmail with wireshark, the
IMAP code looks valid to me.

If I'm to guess what fails is the parsing of the IMAP results into
something that can be put into the Summary buffer.

If I was going to edebug this, what function should I instrument?

I tried doing C-M-x on
 (deffoo nnimap-request-group (group &optional server dont-check info)

But that didn't make the debugger start when entering an nnimap group on
the davmail server.

Thanks!
