I am trying to patch Nautilus 3.2.1 on 11.10 with this patch (dual screen fix).

So I've executed whole sequence:

sudo apt-get install devscripts
sudo apt-get build-dep nautilus
apt-get source nautilus
cd nautilus-3.2.1/
cp ~/nautilus.patch .
patch --dry-run -p1 < nautilus.patch
patch -p1 < nautilus.patch
debuild

And I've got finally fatal error (whole output here):

dpkg-buildpackage: error: dpkg-source -b nautilus-3.2.1 gave error exit status 13
debuild: fatal error at line 1348:
dpkg-buildpackage -rfakeroot -D -us -uc failed

Any ideas?
