What version of Roundcube is that?

Here
[31-Aug-2010 12:00:58 +0100]: C: ftch0 UID FETCH 31 (BODY.PEEK[1])
[31-Aug-2010 12:01:37 +0100]: S: * OK [CAPABILITY IMAP4rev1 UIDPLUS ...
and here
[31-Aug-2010 11:59:33 +0100]: C: ftch0 UID FETCH 22 (BODY.PEEK[5])
[31-Aug-2010 12:00:37 +0100]: S: * OK [CAPABILITY IMAP4rev1...

No response from IMAP server for UID FETCH command. So, this is
definitely a IMAP connection issue. Check IMAP server logs. What's your
imap_timeout setting in Roundcube?

p.s. Courier-IMAP sucks, you know?
