Could you try the attached patch and getting a gdb backtrace from the resulting core file? (Or at least the raw backtrace - getting a core file might be tricky.)

Ah, so the original patch helped! This is a different error.

Simplest solution now would be to make this world-rw, see the auth-userdb socket configuration in http://wiki2.dovecot.org/LDA#Virtual_users

But I guess this should also be fixed by doveadm-server. Although I don't think this should be happening by default anyway. Maybe this is also solved by the http://hg.dovecot.org/dovecot-2.1/rev/476381017ec7 patch?
