Making IBus usable in Kubuntu

[Ma Xiaojun]

IBus is the default input framework for Ubuntu.
It features many input methods.
Asian user would use input methods on a daily base to input their
native languages.

I discovered two blocking issues of IBus on Kubuntu 12.04
1. IBus's GTK icon dependency is missing. (This issue may also exist
in early Kubuntu releases)
The end result is IBus GUI cannot be shown unless "gnome-icon-theme"
package is manually or occasionally installed.
https://bugs.launchpad.net/ubuntu/+source/ibus/+bug/854333
I also reported a similar bug to Debian and the "ibus" package in
Debian is already fixed (before Debian Import Freeze).
However, "ibus" package is in main section of Ubuntu with Ubuntu
specific patches, so there is no auto-sync for 12.10.

2. Kimpanel cannot use IBus backend (Need confirmation since I'm not a
Kimpanel expert)
Kimpanel is said to have more native look and feel in KDE.
There is a package called "plasma-widget-kimpanel-backend-ibus" in
11.10 and earlier.
http://packages.ubuntu.com/plasma-widget-kimpanel-backend-ibus
But this package is gone in 12.04 or later.
Almost all online resource I can find mentioned this package.
For example, the one on kde.org:
http://userbase.kde.org/Tutorials/Kimpanel
On the other hand, "plasma-widget-kimpanel" in 12.10 contains a
libibus dependency.
http://packages.ubuntu.com/quantal/plasma-widget-kimpanel
So it may support IBus out-of-the-box.
How to use Kimpanel with IBus in 12.04!?
