I don't know why this has been happening for some people/under some
situations, but not consistently. gdp is reading the "optimized" versions
of the games' groups and files out of a zip file, which in principle ought
to be seekable; but if it isn't seekable, then why did it ever work?

I've pushed a change which should fix this, at the cost of a small amount
of duplication (the group names now appear in the "optimized" files
twice, so they can be processed correctly without rewinding).
