Do you have any more details about how to reproduce the fault?

I can't initially see what the problem might be, but I'll have another

I do notice that (in the presence of the patch in question) all
references to the static variable fnvb in function
ensure_packagefiles_available() should be safely removable, but I
doubt that this is directly relevant.
