Do you see any errors on terminal if you restart ibus with the verbose mode?
1. Right click on ibus panel and choose "Quit".
2. Run 'ibus-daemon --verbose --xim &'.
3. Choose Anthy.
Are you able to reproduce the same problem with a new user account
instead of the current user account?
The ibus 1.4 is now a bit old to be maintained.
