dovecot - Jun 2010 - R: Re: Dovecot 2.0 shared mailbox using ACLs problem

Hi,
now I'm able to share/access to the shared mailbox,
but when try to write (as owner) in each mailbox, I catch a  segfault of the 
imap process.
In the next the trace.
I'm using "dovecot-2-0-2d6cf78982dc".

gdb backtrace would be helpful in fixing it. http://dovecot.org/bugreport.html

crash?
