If you can easily reproduce the problem (I guess so according to the
above), an experimental patch to diagnose such errors may help.  It
will be available in the next versions of BIND9 (9.6.1 etc), but if
you're willing to test it, please let me know.  I'll send a diff to
you.

BTW, I have no problem in resolving the name in question.
