Have you tried a test decryption on your end?  E.g., encrypt the file
with your own public key and then decrypt that, and see whether the 13
spaces are present?

Also, version numbers would be very useful--both GnuPG on your end and
PGP on the vendor's end.

This may very well be a PGP problem as opposed to a GnuPG problem, in
which case you may be better served on a PGP list such as PGP-Basics at
Yahoo! Groups.

Impossible to say without more information.  My inclination is to think
it's probably on the vendor's end, especially if you're using a recent
version of GnuPG.  There are a lot of PGP 5.0 and 6.5.8 installations
out there, and both of them substantially predate the OpenPGP standard
which GnuPG conforms to.
