Not sure yet. I havent't tried it yet, but I'm sure your solution
helps with the specific problem here. (Also updating the URL helps even
better :-))

What I feel strange here is:

* When the file is already on the local disk, it has to match a certain
file name criteria. Quite hard criteria.
* But when asking outside repositories over the network, we just "take
anything that has the hashsum".

Is that wanted behaviour?
