Hi,

I just got an error message

    dpkg-source: error: '!nogui' is not a valid build profile restriction formula

I guess it is complaining about the debian/control file, but it would be
nice to know whether it is complaining about a Build-Profiles: line, a
restriction on a build dependency, ...

That error message could be a bit clearer on what is the actual problem
here.
