I don't speak perl, but an undefined string seems to be already caught
by the above check. I tried this simple script to see:

#!/usr/bin/perl
if ($version eq "") {
  print "parse error\n";
}

so I think ($version eq "") does the job well enough for now.

Maybe things would be different if sbuild invoked perl using -w,
but if you go that route, there would be a lot more lines to change,
not just this completely minor thing about 0 as a version string.
