Comment 9 for bug 1226282

If you compare https://launchpadlibrarian.net/178524405/buildlog_ubuntu-utopic-i386.mupen64plus-core_2.0-6_UPLOADING.txt.gz and https://launchpadlibrarian.net/178524404/buildlog_ubuntu-utopic-amd64.mupen64plus-core_2.0-6_UPLOADING.txt.gz than you can see that the i386 (the one with the wrong symlink) has an error:

grep: ../mupen64plus-data/DEBIAN/control: No such file or directory

If this grep wouldn't fail than it would be detected that it is an "all" dependency from a non-all package
