Comment 1 for bug 816155

I ran into this problem on https://launchpad.net/ubuntu/+source/kde4libs/4:4.7.0-0ubuntu1 since it build-depends on libjpeg-dev, which is a virtual package. What's really odd though is that after i386, amd64, and armel had hit depwait due to this bug, I uploaded ubuntu2 to build-dep on the real package. Then powerpc and armel (which had previously depwait) built. See (note: build was manually killed by lamot):
