Any guess at what would cause this?

namespace { alias_for = hidden = yes list = no location = prefix = / separator = / }
This one causes these crashes. Fixed in v2.2 now: http://hg.dovecot.org/dovecot-2.2/rev/fb367a977077
Thanks for diagnosing this. I'll probably remove this namespace or limp along until 2.2 becomes the latest stable release.
I added this namespace alias in an abundance of caution: this was to prevent users from trying to peruse the entire file space e.g. /etc. A poor man's chroot. I didn't test this thoroughly to see if it actually did what it was supposed to.
