So I worked with a co-worker to figure out where the problem is.
  In get_nkconfig() in ./lib/loadnkconf.c

                        /* Go to the next */
                        handle = rbtNext(rbconf, handle);
                        if (handle != rbtEnd(rbconf)) {
                                rbtKeyValue(rbconf, handle, &k1, &k2);
                                if (strncmp(realkey, ((nkconf_t *)k2)->key,...

  here k2 is treated as a pointer to a nkconf_t
  but it appears that it is really a 'char *'.

Is what he concluded from our poking with gdb. We haven't gotten
any further in debugging, but hoped this would help to pin down
the problem.
