Is it fair then to only include gtk2-engines-xfce? It should include all
the gtk2-engines or none. And I would say "none". It is the users job
then to install the needed gtk2-engines-* packages for both amd64 and
i386 if at all. Similar to pam modules when being required in amd64 and
i386 or input methods for gtk. We don't have a good way to automatically
force them to be installed for amd64+i386 under multiarch as needed yet.

It will apply there too. Multiarch just changes the file locations. It
won't change the basic behaviour of gtk. So while this seems
uninteresting for ia32-libs-gtk itself, I should probably drop the
dependency, it will be of relevance for users. So gtk2-engines-* should
probably all be multiarchified.

Is there a mailinglist for gtk2-engines-* packages where this could be
discussed with the right audience?
