Michael fixed this in devel. Thanks Michael! I should probably backport
the fix to release.
@Ben: FWIW subsetting with an IntegerList subscript is much more
efficient than with an ordinary list:
index <- rep.int(IntegerList(index), length(object))
object[index]
It will make a big difference (e.g. 100x faster or more) if 'object' is
a DNAStringSet with tens of thousands of sequences.

This puzzles me as I know the function is part of IRanges, which is imported in the package, and I would assume Biostrings would import any IRanges functionality it needed for the DNAStringSet indexing operator.
