back-hdb crashes config engine if back-bdb is also present.

How to reproduce:

edit slapd.conf and load both hdb and bdb and create an hdb database.
eg:
moduleload      back_bdb
moduleload      back_hdb

database        hdb
...

start slapd
add a few entries to the hdb database suffix
stop slapd
restart slapd

GDB on slapd.core
