The keyboard shortcuts to change input mode are not working #114

This is a copy of the bug report on my distribution 
https://bugzilla.redhat.com/show_bug.cgi?id=771799

Description of problem:

First, forgive me if it is a user mistake.

I have installed ibus-mozc from the fedora repo. Default installation. 
Conversion shortcuts work fine when I input words. However the shortcut to 
change input on
the language bar:

- Direct input
- Hiragana
- Katakana
- Latin
- Wide latin
- Half-width katakana

are not working.

For what I have seen on my system:
- Composition/Precomposition | Hiragana | Set input mode to Hiragana > Not 
working.
- Composition/Precomposition | Muhenkan | Switch kana type > Not working.

I created a custom shortcut:
- Precomposition | Ctl+. | Switch kana type > Not working


Version-Release number of selected component (if applicable):

Name        : ibus-mozc
Arch        : i686
Version     : 1.3.911.102
Release     : 1.fc15

I am using Fedora 15 (en_US) on a Japanese notebook.


How reproducible:

Always


Steps to Reproduce:
1. Switch to ibus-mozc input
2. Any shortcut to change kana/latin/direct input are not working

Actual results:

Selection by a right click on the icon in the language bar, and one more click
on the kana selection.

Expected results:

Switching kana/latin with from the keyboard


Additional info:

I can use the default shortcuts (see above) with ibus-anthy.
