Subject: [PATCH] Prevent crash while reloading previously invalid but now
valid DNS zone.
The crash happened under these circumstances:
- a DNS zone (test.) has NS record relative to this zone (ns.test.)
- the name pointed to by NS record did not have any A/AAAA records
- restart BIND to enforce zone load
- zone loading failed because of invalid NS record
- missing A/AAAA record for name ns.test. was added
-> CRASH!
