Multiarch is well defined and implimented for libraries but for these
executables used by other software, the best practice was not clear to
me and may had some wrong handling.

Package: ibus
Architecture: any
Multi-Arch: foreign
...
Recommends: ibus-gtk3, ibus-gtk, ibus-qt4, ibus-clutter, im-config | im-switch
...
Package: ibus-gtk
Architecture: any
Multi-Arch: same
... 
Package: ibus-gtk3 Architecture: any Multi-Arch: same

ibus being "Multi-Arch: foreign" it can serve both i386 and amd64
applications by either one of ibus:i386 and ibus:amd64 but ibus:i386 and
ibus:amd64 are not co-installable.

ibus-gtk:i386 only serve i386 program because it is "Multi-Arch: same".
ibus-gtk:amd64 only serve amd64 program because it is "Multi-Arch: same".

Hmmm... so this is expected problem of current packaging which we have
no easy solution.  This should be true for current testing version too.

Question is how to solve this.  Making ibus-gtk and ibus-gtk3 and ... to
Multi-Arch: foreign solves this?  i do not know the answer.  Aron what
do you think?
