Comment 2 for bug 1226282

I've looked at http://packages.ubuntu.com/quantal/libmupen64plus2 and compared the changelogs. The i386 version has a symlink to mupen64plus-data and the amd64 one has the real changelog. This is not how the Debian package was made and therefore I would guess it is caused by the Ubuntu build system.

And I would also guess that you don't need libmupen64plus2:i386 because the other packages you are using are :amd64. So please try to remove libmupen64plus2:i386.

Maybe someone here knows who is responsible for the ubuntu build system and the multiarch implementation in Quantal, raring, saucy, .... and can subscribe them to this bug
