There is no "matching expression", at least unless you supply one.

If the two packages are the same upstream version and using source
format 1.0 then the diff.gz files are passed to interdiff; otherwise,
the two source packages are unpacked using "dpkg-source -x" and "diff
-Nru" is run over the two trees. "-N" is "treat absent files as empty",
which would explicitly request that the new file be included in its
entirety in the diff. The only time anything is excluded from the diff
is if you pass "--exclude" to debdiff on the command line.

In order to be able to try and reproduce this, we would need copies of
both source packages (or filenames if they're already in the Debian
archive) and the exact command-line being used.
