Usermin IMAP error in Virtualmin Pro 3.57

Don't know if this is related to the latest update applied last night, but here it goes:

many usermin users are getting this error, some pop3 users are reporting errors too:

Failed to open IMAP mailbox : Internal error occurred. Refer to server log for more information. [2008-05-19 10:19:50]

the log says:

May 19 10:19:50 sotol dovecot: IMAP(oscar.beltran.rapigas): write_full(/home/rapigas/homes/oscar.beltran/Maildir/dovecot-uidlist.lock) failed: Disk quota exceeded

the user has 100mb quota, 46mb used
