Thanks for fix of multi-arch for im-switch.  I am about to fix in im-config
package side.  (Since im-switch is not used for ibus now, I do not know use of
this as is but if we make changes as below, it is useful for wheezy.)

This is very deep question.  

But practically thinking, control file needs update to fix this problem:

Now we have:
Depends: ${shlibs:Depends}, ${misc:Depends}, ${python:Depends},
 python-ibus (= ${source:Version}), python-xdg, librsvg2-common, python-notify, im-config
Recommends: ibus-gtk | ibus-qt4 | ibus-clutter
Conflicts: ibus-anthy (<< 1.2),
 ibus-table (<< 1.2),
 ibus-pinyin (<< 1.2.99),
 ibus-m17n (<< 1.2.99),
 ibus-hangul (<< 1.2.99),
 ibus-chewing (<< 1.2.99)

I think correct thing to do is:
Depends: ${shlibs:Depends}, ${misc:Depends}, ${python:Depends},
 python-ibus (= ${source:Version}), python-xdg, librsvg2-common, python-notify
Recommends: ibus-gtk3, ibus-gtk, ibus-qt4, ibus-clutter, im-config
Conflicts: ibus-anthy (<< 1.2),
 ibus-table (<< 1.2),
 ibus-pinyin (<< 1.2.99),
 ibus-m17n (<< 1.2.99),
 ibus-hangul (<< 1.2.99),
 ibus-chewing (<< 1.2.99)

So they all get installed as defualt, if admin choses not to do so, he should
deal with it.  im-config has option to force using xim as default too.

If we can move all im packages to use im-config as recommend, then we can drop
overcomplicated im-switch script for most people.  If someone imsist after
wheezy, he can manually install it. (Or chose any other local method.  I do not
think im-config should be Depends as its upstream.)

As for im-switch script, we release package to check both gtk3 only if GNOME is
moving almost all to gtk3.  Then remove this script altogether after wheezy.
