Please test new dpkg in experimental
I just uploaded a new dpkg to experimental (so it is in incoming
currently) which features significant changes to dpkg-shlibdeps that
hopefully get rid of both the problems with biarch builds and with
I have made some tests that indicate it really fixes these problems
but I would encourage you to verify that yourself and report wether
it's true or not.
Unless there are any big problem it is planned to upload this dpkg
version to unstable at the end of the week.
