Do you have any nntp servers in use?  It looks as if this problem comes
up when some sort of authentication is involved, as is with Tassilos
IMAP, your POP3 and one of my nntp servers.

Can just remove the nntp server from my select methods without any bad
effects to see if the problem is still there without it?
