dovecot - Apr 2010 - Core dump in 2.0-beta4 and latest Mercurial

I'm seeing core-dumps with both 2.0-beta4 and a fresh checkout from 
Mercurial. I'm very new to Dovecot, so there's a good chance this is 
caused by my limited experience with Dovecot configuration, but it's my 
understanding that any core-dump is considered a bug (nice policy by the 
way).

The installation seemed to be working as expected until I added the two 
namespaces and tried to set up shared mailboxes.

Timo: The installation is running on a KVM dedicated to testing Dovecot, 
so if you want to debug anything in my environment, just send me your 
SSH key, and I'll set it up.


Attached files (from test with latest Mercurial):
-------------------------------------------------
dialog.txt: IMAP dialogue to reproduce the core dump
mail.info.txt: Resulting log entries
debug.log.txt: Resulting debug-log entries
bt-full.txt: br full for dumped core

I can't really understand why rootdir=NULL, but path isn't NULL. I
couldn't reproduce it in my few tests. But I guess it doesn't matter all
that much, this fixes it:
