It's caused by the fts plugin, which is kind of annoying to touch :) I'll try to get around to looking at the crash soon..
Well, it's simply missing code. fts_squat and virtual don't work together right not. There are two ways to fix this:
a) Build separate squat indexes for the virtual mailbox
b) Use existing squat indexes from the backend mailboxes.
b) would probably be better, but also requires more work. So for now I just implemented a): http://hg.dovecot.org/dovecot-1.2/rev/96b764649cbb
