Error when opening a mail with attached images

[Kilrathy]

Hey guys

just did an fresh installation of RC 0.7-beta - everything works fine, exept, when I open any mail with attached images. On every mail, roundcube reports some nasty errors:

Code Select Expand

Dec  9 15:05:19 luffy roundcube: IMAP Error: Login failed for #####@##### from 10.78.200.20. LOGIN: LOGIN failed in /srv/htdocs/#####/webmail/program/include/rcube_imap.php on line 205 (GET /?_task=mail&_action=get&_uid=3&_mbox=INBOX&_part=2)

This error happens even when I use an imapproxy or not. Fortunately, I can open the mail and see the images.

Any ideas?
