[Dovecot] assertion failed: (mailbox_list_is_valid_existing_name(_list, name))

[Adam McDougall]

When I was initially testing dovecot 1.1b2,3 I had ACLs turned on and encountered
this problem below.  I had them turned off until now, I'll need to have ACLs working
before I can widen testing.  I'm not sure how to make "env MAIL=maildir:~/Maildir gdb 
/tmp/imap" load the ACL plugin so I assume that is why it does not crash; not getting
any log either from that, maybe I made a mistake?  But when running mutt, I can load
it up with the inbox, then when I ask for imap://server/mail/ it crashes with the 
assertion at the bottom.  Let me know if I need to provide more info.  Thanks.
