dpkg-source: unrepresentable changes to source

[for.ad@free.fr]

hello,

I'm trying to build a source and a binary package and I would like to add some
files like pixmaps in the archives.
My Pixmap file is in the debian/pix/ folder and while 'dpkg-source' build the
diff.gz I got a 'unrepresentable changes to source'
