I see, I have some problem with this patch no matter which version I use.
I've tried 1.0.2, 1.0.5 and 1.0.7 and it always fails in the same point.
dovecot.log says:
Nov 12 11:38:41 Error: child 27295 (imap) killed with signal 11
It happens on FETCH command, other commands seems to work ok. I've noticed
that if maildirsize is absent it should be rebuilt after FETCH command. It
works well on unpachted version.
My OS is Debian Stable on x86. Maildirs are on NFS (Linux server).
Configure command was:
./configure --prefix=/var/dovecot --with-ioloop=epoll --with-sql-drivers
--with-sql
--with-mysql --with-notify=inotify --without-pop3d
and result of configure was:

I see that segfault is caused by uninitialized (deleted?) qt variable, but I
have no skills to trace it.
If you want more info please ask, I'll do my best.
