dovecot - Jul 2009 - fts_squat + virtual => crash

Hi,

dovecot's imap process segfaults when I search a virtual mailbox using
the fts_squat plugin. Is this supposed to work, or a known bug?
I've seen some changes commited to fts_solr a couple of months ago
that where supposed to fix search issues on virtual mailboxes, maybe
fts_squat needs to be fixed to?

backtrace
========
As I'm using Debian's 1.2.1 package, the debugging symbols
are stripped. Tell me if a backtrace with debugging symbols enabled
would help debugging this problem.

Here's the backtrace anyway:

A quick test shows that it works with me.

No, Squat works differently and doesn't have the same problems.

Yes, backtrace with debugging symbols would be very helpful.
