Comment 9 for bug 1416375

Oh I see what you mean. It has nothing to do with the present patch—rebuilding the current source package with no changes results in a non-working source package.

Is this a dpkg bug?

A workaround is to delete debian/source/options (which contains ‘single-debian-patch’) after extracting the package.
