It may very well be that the test can be improved, but it was triggered
by a hard-to-diagnose failure where an XML file had us-ascii encoding
declared, but contained non-ascii characters.  The RPC didn't manage to
get a handle on what the problem was that triggered the failures, and it
also took me a while to understand what was going on.
