Well, now we know.

         // up to now we can only read files of version 0.9.3 and earlier
         // there was an xml format change  in 0.9.4

The error message is useless, but the real problem is Rosegarden doesn't 
support the current version of Hydrogen's XML.

Rewrite required.

Investigation shows someone was interested in looking at this problem in 
2010 and allowing Rosegarden to support the several different version of 
Hydrogen XML.  It came to naught in three years.

I didn't dig up a map to Hydrogen's current XML, which is different from 
the version used by the file I've been trying with, which is different 
from the version Rosegarden supports.

That's all I need to see.  Practically nobody ever noticed that this 
feature was broken, and it has now reached the point where it would 
require a great deal of work to get it working again.

I'll look at the MIDI import problem next.  That's the use case I'll 
worry about.  Hydrogen import is gone.
