Redcar redcar

Hi,

When I was dealing with Japanese text on Redcar, it freezes when I scroll up and down the window by mouse(Try copy and pasting http://ja.wikipedia.org/wiki/%E6%97%A5%E6%9C%AC to replicate).

Most of the time, my machine completely freeze with cpu 100%, but it once crashed with the following errors when I was doing scroll down by hand(using keyboard shortcat).
I use OSX 10.6.4(Snow Leopard) and installed redcar about a few days ago. Please let me know if you need more info.

Thanks.

Makoto
