I don't think so. The dh-python dependency is a much more likely candidate,
but that's a build dependency. But it's hard to say what the cause of the
issue is without at least having a copy of the control file that you used.
Better yet, send me the entire .deb you built in private mail so that I can
have a look.

Yeah, Debian packaging is a real nightmare. I have no doubts that it was
actually invented by the Vogons. ;-) And it doesn't help that I have little
to no experience with those low-level tools like dpkg-deb. I always use
debuild instead.
