[Dovecot] dovecot 2.2.5 with plugin listescape and shared mailbox with dot in INBOX

[romain]

Hi list,

I have a problem with dovecot 2.2.5 and nightly (latest 20130923) with :

  * plugin listescape enabled
  * shared mailbox
  * and mail_shared_explicit_inbox = no

Problem is I can't get list of mails in INBOX of my shared users.

For example :

/home/dovecot/dovecot//mail/l.dupont/Maildir/.Other 
Users.l\2edupont/dovecot-acl not found
----------------------------------------------------------
Last line see that the Shared Mailbox "Other Users/l.dupont" is 
converted to "Other Users.l\2edupont"
Note, that this does not append when I trie to access a subfolder like 
"Other Users/l.dupont/Sent"

If I set "mail_shared_explicit_inbox = yes" with plugin listescape, I 
can access "Other Users/l.dupont/INBOX"
If I remove "listescape" from my plugin directive, I can access the 
INBOX of "Other Users/l.dupont"

Thanks for any help :)

Regards,
Romain
