--- Operating System, Graphics card ---
Debian Unstable AMD64, Intel graphics

--- Blender version with error, and version that worked ---
Blender 2.69.1, built from SVN Sunday October 13.

--- Short description of error ---
Render shows fewer particles than 3D view

--- Steps for others to reproduce the error (preferably based on attached .blend file) ---
The enclosed .blend file uses a particle system to cover the cylinder with greebles randomly chosen from a group of simple objects. I also enclose a screenshot of the 3D view and a final render. The final render shows noticeably fewer particles than the 3D view--note the empty spaces near the top of the nearer end face, as well as a few other places. How is this possible? The display percentage is set at 100, so they should both be the same, should they not?
