keying smoke amount -> Fatal Error Maya 2013/14

[dagoose]

Hi,

I'm emitting only smoke from a particle source (standard maya volume emitter) for a couple of frames. I want to stop emitting in frame 10 but keying the smoke amount value down to zero maya crashes with a fatal error. I tried this twice in maya 2013 and also one time in 2014. It is always crashing after keying the value to zero.

Okay further more ... creating a grid and a particle source keying any value -> crash !

radius -> keyable
valocity mult -> crash
smoke amount -> crash
smoke variance -> keyable

Thanks for your help.
