IMAP sessions quit when calling MYRIGHTS on shared namespace

Hi,

  the IMAP connection is dropped, when I call MYRIGHTS on the root of my
shared folders.

Using the configuration below, the shared folders are located in shared/%%U/

# telnet localhost imap
Trying ::1...
Connected to localhost.
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE
IDLE STARTTLS AUTH=PLAIN] Dovecot ready.
. LOGIN XXXXXXX xxxx
. OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE
IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS
THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN
NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH
ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE BINARY
MOVE QUOTA ACL RIGHTS=texk] Logged in
. MYRIGHTS shared
Connection closed by foreign host.

I'd expect some kind of error message instead of dropping the connection.

Kind regards,

Franz

Did you've looked in your server log? You most likely got an abort or 
something like that.
