Thank you Timo for the quick fix,
here we have latest rc3 in a production environment.
It has been used by over 600 users in the last 2 days.

The most failing assertion (9694 times in 2 days) is the one I posted yesterday:
Panic: IMAP(username): file index-sync.c: line 39
(index_mailbox_set_recent_uid): assertion failed:
(seq_range_exists(&ibox->recent_flags, uid))

It happens when users are moving messages to Trash folder with thunderbird.
The workaround for the user is to delete directly the messages without
moving them to Trash.

We had also some trouble with pop3. A couple of users weren't able to
get new mail (see log below) until we deleted completely their .imap
dir.

Diego.
