dovecot - Feb 2013 - 2.2.rc2: problem with acl_shared_dict

Hello,

2.2.rc2, configuration as before:

acl_shared_dict=file:...
The contents of this file is used for e.g. LISTing shared mailboxes.
But even with file and directory beeing world writable, it's not written
into on SETACL commands.
Instead, at least sometimes (it seems to make a difference if GETACL is
used before in the session) the imap process crashes on SETACL or DELETEACL.

Feb 26 00:31:52 host dovecot: imap(13373, user) K64y8ZTWOgB/AAAB: Fatal: master:
service(imap): child 13373 killed with signal 11 (core dumps disabled)
Anything to do for further debugging? Working correctly with 2.1.15.

Greetings,
  Lutz

I couldn't reproduce with a few tests, so gdb backtrace would be
