What steps will reproduce the problem?
1. Install OSS Mozc 1.5.1090.102 (r115) into Ubuntu 12.04
2. Run Chrome 21.x or Firefox 15.x
3. Open
4. Type something.
5. Select some characters.
6. Hit "Henkan" key to invoke reverse conversion.

What is the expected output?
Selected characters will be reconverted.

What do you see instead?
Nothing happens.

This comes from a limitation of GTK immodule:

ibus-gtk has supported selection text retrieval only from GtkTextView.
| Currently only GtkTextView widget can get them in gtk application.

Since Mozc's reverse conversion protocol requires the selection text, we cannot 
use reverse conversion on many applications including Chrome and Firefox.

To work around this limitation, we can use X11 text selection buffer. Actually 
ibus-anthy uses X11 text selection buffer to implement reverse conversion.
