Comment 1 for bug 252776

Error handling in general probably needs some cleanup. For example, if dpkg-source spits out an error message, it has failed to build the package, but the build plows on, with no indication that there was a problem, except that the /bin/rm commands at the end of the process fail because the files being deleted aren't there. The only way to tell it failed is to read the entire build log, which might be cryptic.
