Input Method Editor can't be used on Mac

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Enable Japanese Input Method, for example, by going to System Preferences
> Language and Text > Input Source, then clicking on Kotoeri (and U.S.)
2.Start Luke, open some index, Sarch Tab, move the pointer inside the
search expression box.
3. Click on the Input Menu icon ("A" or US flag) on the menu bar near the
battery indicator, and choose Hiragana.
4. Type "a".  You'll see the letter "a" as though no Input Method is in play.

What is the expected output? What do you see instead?
"あ" should be displayed in this case.


What version of the product are you using? On what operating system?
Luke v 0.9.9 on MacOS X 10.6.2.
