I couldn't reproduce it with your config, but I figured out the cause of it anyway. Fixed: http://hg.dovecot.org/dovecot-2.1/rev/6b9db780b47d

segfaults
with location is fine

without type = shared there is no segfault,
I understand this config might not work (invoking imap directly) but it should't segfault.
