Hello together,

yesterday I came across a building issue when building a package for
unstable using pbuilder. The symptom is that "dpkg-source -b" terminates
with error code 127 without further notice.

I have reported the problem upstream and it was confirmed as a bug. The
bugfix is already on its way:

cheers,
Andreas
