Yeah, sounds that way :-(

Probably not much, so far as this copy of the file is concerned. My first
guess as to what happened to it is Windows to non-Windows (or vice versa)
newline conversion, which could add or remove bytes and thus mangle the
file's archive structure. How did you transfer the file across machines
exactly?
