Summary:
Particles ignore object speed
Detailed description
In the appended example file in which i added a particle system to the cube. It set the value "Object", found under "Velocity->Other", to 1. So i would expect the particles to have the same initial speed as the object (the cube) itself. But the particles just fall to the ground with no starting speed whatsoever.
Blender r50773, 64 bit, Ubuntu 12.04

Are you sure it's assigned to the right person? :)

I don't know why this crap doesn't work, it seems the object transform does not change during the frame if you set start=end time ... Somebody else might do it, i'm not going to waste more time on it.

Emission starts and end at exactly the same time. frame 50.
It is not enough longer to transmit object's velocity to particles.
It works correctly if you precise Start to 49.999 and End to 50.000.
Be carefull values does not refer to the same frame. Start at 50.000 and End à 50.001 does not work.

Right, to have obspeed work the particle system needs to have at least 2 time steps, that way it detects speed of things.
No bug!
