In this case, back-mdb never expects the number of indexed attributes to be
zero. (At the least, objectclass must always have an equality index.) back-mdb
can be patched to avoid this particular crash. But as a rule, you're expected
to make all changes to the index config in a single Modify op. Not delete all
the indices in one operation, and then define new indices in a new operation.
