Easiest way to figure these kind of things is to set
mail_executable=/tmp/dump.sh which contains:

#!/bin/sh
set > /tmp/dovecot.env

And run dovecot --exec-mail imap. Then either use that information or
just run ". /tmp/dovecot.env" before gdb imap.

Fixed the crash: http://hg.dovecot.org/dovecot/rev/7373240c3d1d

But the real problem is that dovecot-shared file is owned by a group
that your imap process doesn't belong to. You probably want to add it to
mail_extra_groups.
