System Information
Archlinux
GTX 460

Blender Version
Broken: 6b81ee6, 2.73

Short description of error
Motion blur fails on object parented to rigid body

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

Open motionblur_fails_on_specific_setup.blend
Simulate the rigid body sim
Pick a frame where the monkey is in frame and render
The hat appears messed up
Disable motion blur and render again
Hat appears normal

Seems like particles are broken again. Rendering without particles works fine, as long as you bake the rigid body sim (that's always highly recommended for motion blur). You can make 2 copies of the hat object to work around it, one invisible to serve just as particle emitter, the other for rendering with motion blur.
