  [a note about not 'receiving' emails from gmail, that I didn't
  precisely understand]

I have seen some odd behavior that may or may not be related.

I use gnus (from git master), emacs 23.3 (most recent release), NetBSD
5.1_STABLE, dovecot 1.2.latest.   Generally things work fine.

Sometimes, I find that a message in my IMAP INBOX does not appear in the
summary buffer.  I see the message with other IMAP clients (thunderbird,
Mail.app).  I can ^U M-g and still not have the message appear.  If I
move the message to another folder and move it back, often it will
appear.

I have not managed to read the debug logs to figure out what's going on.
(Usually when this happens it's a message I have to deal with for work,
and I do that and move on, not having spare gnus-hacking time that
moment.)  Because my bug report is lame, I haven't yet sent it - but am
speaking up now because it may be a different manifestation of the same
problem.
