Desktop application freezes when I use Mozc 1.2.831.102

[GoogleCodeExporter]

What steps will reproduce the problem?

1.Open any desktop application you can input Japanese 
   (eg: gnome-terminal).
2.Type in charactors and terminate the application.

What is the expected output? What do you see instead?

Everything was OK until I was using Mozc 1.1.773.102, but after I 
upgraded to Mozc 1.2.831.102, the application takes a long while to actually 
terminate (almost freezing). After that, I cannot start up any desktop 
application until I terminate Mozc with "killall  mozc_server"
(window manager works OK).

What version of the product are you using? On what operating system?

Mozc 1.2.831.102
Ubuntu 11.04

Please provide any additional information below.

Following is what I got from dmesg output

    [230087.231382] scim-launcher[29364] general protection ip: 334645 sp:bfe9cce0 error:0 in mozc.so[2b8000+e6000]

Actually, I created a new user in my system for test purpose. Mozc 1.2.831.102 
works OK with this new environment.
I am carrying my environment over many years so maybe this is  something to do 
with my setting. However I have no idea about what does this error message mean 
and what should I check with my environment.
