Is that something that worked in earlier versions? There is nothing
that I can think of that might have altered that.

OK, it is a bug that an error is thrown like that, but in any case the
indexing code will not work if given gmapsupp files rather than
individual tiles. It would be possible to make it work, but it is not
a simple change.
