firefox 4 language display problem

[han9k]

Binary package hint: firefox

When I set my starting page to "google.com" in Firefox 4 (ubuntu 11.04 b1), firefox displays strange language which is either English or my own language(Korean).
I was messing with "usr/lib/firefox-4.0/searchplugins/" folder and removed "en_ZA" folder to see if the setting in that folder caused the problem.
Somehow it seems that the problem disappeared temporarily for the moment.

I am not sure if this is the permanent solution but I would like to report this problem since firefox 4 in my Windows 7 didn't cause the same problem but only with Ubuntu 11.04 b1.

This problem also appears when I try to use the search box located at the top right corner with "google" search engine.

I'm using:
ubuntu 11.04 b1 (32bit, i believe)
firefox 4 (the default internet browser in 11.04)

system language: Korean/English (I change to one another often)

same problem exists in Firefox 4.0.1

to fix this problem,

delete en-ZA folder located in
/usr/lib/firefox-4.0.1/searchplugins/

and reboot
