This is more an email for the discuss list, rather than developers.
But the answer is that this is a feature of the InChI, not a problem.
It normalises some tautomers. The \h1H,(H,2,3,4,5) means that the
atoms 2, 3, 4 and 5 (the numbering is specific to InChI) share one H
(as far as I remember).

I hope someone can shed some light on the two attached files. I created them
with http://molcalc.org/:

http://molcalc.org/calculation/b7a6e900f56389dca53aba08000bda33
When I run openbabel on them I get the same InChI for both
