[Dovecot] 1.1.2 segfaults when using passdb passwd and md5 mechanism

Setting passdb to passwd and enabling cram-md5 or digest-md5 makes
dovecot crash.
The documentation says that I can use md5 with passwd. I had to use
strace to figure it, because dovecot segfaults and doesn't log the
error.
Using CenOS 5.2 x86_64
