Could you give me a little more info on your bug report #18511 please. Are you able to reproduce this with a current version of dpkg? If so could you send me an example of the directory you are trying to build (tar.gz of the directory would be fine, small please), so I can try to reproduce this and be sure it's not a problem in the setup (note, I've tried building packages this way a lot of times, with no problems). Thanks, Ben
