I concur.

Without a core dump, and without an indication of the operation that
caused it tracjing the bug down is a bit awkward.  Can you provide at
least more details on the operation (relevant slapd.conf, LDIF or
equivalent that caused the problem, or a tcp dump of the communications
between the client and the server).  My first guess by looking at the code
is that the problem occurs while adding an entry whose parent does not
exist.  Also, note that back-meta was heavily reworked since 2.3 is out,
so I'd suggest that you check if the problem persists with that version. 
Bugs in 2.2 will be fixed only if extremely required, given the very
limited usefulness of back-meta.
