[Dovecot] Dovecot 1.1.4 / Maildir++ quota and move to trash

Hello,

Seems there is some nasty problems with Dovecot 1.1.4...

We use Maildir++ quota, and when moving mail to Trash, Dovecot just
drop the connection... when the maildir is overquota.

Is there any way to avoid that and just move the mail to the trash
allowing user to expunge their mail easily without calling support to
do rm -rf Maildir/cur ?

Thanks, /Xavier
