Mac OS 8.6: Crash With Password Security and Japanese Language Kit

I have a PowerBook G3 with Mac OS 8.6 and Japanese Language Kit 1.2 and the Language Kit Updater installed. If I have Password Security turned on, my computer crashes with a type 11 error when I switch to the Japanese Input Method. If I turn off Password Security, I can switch to the Input Method without crashing. Why is this happening?
Apple has identified an issue with the interaction of Password Security 2.0 and Kotoeri (Japanese Input Method) under Mac OS 8.6. To work around this issue, turn off Password Security when using the Japanese input method. This issue is resolved in Mac OS 9.
