LYX will crash when changing the Toolbar icon's size

[asm23]

Hi, I'm using Lyx 1.6RC3. I install the Lyx with Chinese language UI. 
When I right click on the ToolBar, and try to select another size of 
icons. Lyx will crash. It seems that not all the menu's were fully 
translated from English to Chinese.

As a solving method, I reinstall Lyx with English language, the crash 
never happened again.

Thanks you!
