I understand the crash below is caused by filesystem quota. I just report it because perhaps it could have a more graceful failure.

Fixed the crash: http://hg.dovecot.org/dovecot-2.2/rev/1d6f42853492

Also fixed a few other mbox issues. But I see that there are still others left when running dsync+mbox. I'll try to get them fixed, but mbox isn't very high priority format..
