Comment (by dobenour):

 I have a patch.  It doesn't solve the problem completely, but it solves
 the problem in `loadArchive()`.  Failures in that function now cause an
 error return and a message to be written via `errorBelch()`.  This isn't
 great, but it is better than the current situation.

 Currently running `./validate --slow` to test.
