I saw you merged fixes for almost everything but your fix for the trigger
part is not complete enough. I pushed again a new patch in
pu/multiarch/for-guillem (it's also attached).

The fact that the pkgbin pointer is stored in the filetriggers list is a
bit unsatisfactory as it might become stale when the package is installed
(i.e. it should in theory be updated to point to the installed pkgbin
instead of the available one). Though in practice the cases where the
pkgbin for available will be updated to something else in the same dpkg
run are close to zero.

    fixup! Update triggers support to understand multi-arch
    Passing pkgbin is not enough, one must also make use of it...
