IMAP problem

[Jens Gorm Rye-Andersen <jens@abk.auc.dk>]

Hi

I am new to gnus, so this may be a simple problem, but I have
been unable to find a solution in the manual or by searching google :(

I read my mail from 3 imap servers. Two of these servers work fine, but
whenever gnus try to open the last server I get the following error
message:

"error in process filter: Internal error, tag 18 status BAD code nil
text STATUS Too few args (empty list)"

I can still access the INBOX on this server and read my mail, but every
time I press "q" to exit to the group buffer gnus hangs with the
message "Settings marks in INBOX...". From this point I can only cancel
by pressing C-g and switch to another buffer with C-b.  

I used mozilla-mail before converting to gnus, and mozilla had no
problem with this IMAP account. The MTA on the server is Postfix and the
imap daemon is mailutils-imap4d.

Any help would be appreciated.

Cheers, Jens
