Bug#46231: dpkg-dev: dpkg-buildpackage fails

[Brian Almeida <bma@debian.org>]

Package: dpkg-dev
Version: 1.4.1.11

When doing:

debuild -sgpg -pgpg

I get this:

dpkg-deb: building package `icqnix' in `../icqnix_0.1-2_i386.deb'.
signfile icqnix_0.1-2.dsc
/usr/bin/dpkg-buildpackage: test: =: unary operator expected
