[Dovecot] Dovecot quoting problem?

[Gerhard Wiesinger]

Hello Timo,

I think the following commit makes problems:
http://hg.dovecot.org/dovecot-2.2/rev/68a8b650578e

# Doesn't work
A01 LIST "" ~/Mail/Gesendet
# OK with quoted mailbox
A02 LIST "" "~/Mail/Gesendet"

A02 OK List completed.

A04 STATUS "~/Mail/Gesendet" (MESSAGES UNSEEN RECENT)
* STATUS ~/Mail/Gesendet (MESSAGES 0 RECENT 0 UNSEEN 0)
A04 OK Status completed.

Is this a bug of dovecot or a bug of the IMAP client (roundcube mail)?

Thank you

Ciao,
