Broken: Probably with introduction of deformation motion blur.
Short description of error
Motion blur together with rigid body simulation produces wrong and arbitrary blurred images.
Exact steps for others to reproduce the error
A .blend file is attached with a cube as test rigid body and motion blur enabled.
- Step a few frames forward to generate some simulation data and motion
- Click "Deformation" checkbox in motion blur panel
- Render image, again and again and again... see the differences. Some extreme renders are attached here.
- Notice also that the rigid body continues the simulation one frame at a time although you're rerendering the same frame
