CL has contact me about this bug. So, yes they are listening. This really cheers me up. I'll keep y'all posted! In the mean time I've isolated the trouble, hopefully I can spare you from a wasted animation render. Dont't use the 2d motion Blur option in the "Make Movie" options in conjunction with Fire Fry. I'm currently testing the 3D blur tool in the render options pallet and Fire Fry is not doing well there either. Stay Tuned...
