MoreIchatEffects and Snowleopard 64 bits

iChat and Photobooth crashes only with SnowLeopard on 64 bits. I have submit the bug to Apple.

But you can launch iChat and Photobooth in 32 bits only (+I or Command+I (not L but i like iPhone) on iChat.app and Photobooth.app).
In this case you have no error and no crash.
