it was not needed to test ALL other downloaders, i said "another downloader", anyway it is an interesting information to have tested all others.
but more important than testing all others was to make other tests i told. i listed 4 tests, and you made only test#2.
test#4 is the one that best will tell us if it is really an HFS issue.
test#3 is the one that may give us some information about fixing.
test#1 is less important.
i'm sorry to ask you all such things, but the only way i can fix the bug is to reproduce it myself, or to know enough about it, and at the moment either conditions don't apply.
