dh_testdir: debian/control has a duplicate entry

Hello,

I’m building debian and ubuntu packages on build.opensuse.org, and I have a problem.

The thing is, if the source tarball contains a “debian” directory, the build fails with
dh_testdir: debian/control has a duplicate entry for gsmartcontrol
make: *** [clean] Error 1

If there’s no “debian” directory in the source tarball, everything builds just fine.
There are no duplicate entries in any of the control files.

You can check my OBS project at
https://build.opensuse.org/package/show?package=gsmartcontrol&project=home%3Aalex_sh
(Novell login required).

The files in question are - gsmartcontrol-0.8.1.tar.bz2 (no debian directory), gsmartcontrol-0.8.2.tar.bz2 (contains debian directory).
