Yeah. That is one reason why I droped it already in the ia32-apt-get
branch. Policy 8.2 already forbids libraries to have conffiles, shared
data, binaries and so on. So anything that breaks by dropping the
i386->amd64 dependency will near certainly violate Policy 8.2. So if
things break a bugreport is in order instead of the ugly dependency
workaround.

Don't worry, this is pending.
