yes, you should be using dpkg-buildpackage to build .debs, it might have something to do with missing icon. I believe qwerty12 explained how to fix the problem with dpkg-buildpackage. If those instructions are not helping, I have to ask you to post the error message and maybe the whole source package here. Otherwise we are, again, just guessing
