Why does changing scale from 0.01 to 0.1 ruin my animation?

Why does changing scale from 0.01 to 0.1 ruin my animation? I had very nicely animating characters and now it looks like:

The character is somehow crumpling in on itself. The animations are executing, but it is all messed up now. I assume if I change back to 0.01 it will work again…but still. I want to scale my models up…

edit in fact, this is verified: if I change my scale back to 0.01, but scale the game object * 10 I get the desired visible result.

edit the animation is a skinned animation. does this make a difference for import?

This problem has been fixed in 4.1.
