%%%--- Operating System, Graphics card ---

Linux Mint 14 "Nadia" 64-bit, GTX 680 with Intel Core i7 processor
Windows 7 Professional 32-bit, Intel Core i5 processor with built-in graphics card
Mac mini (late 2009) with Snow Leopard 10.8.6 (I think), Intel Core 2 Duo Processor with built-in graphics card
- Blender version with error, and version that worked ---
  2.66 (r55075:55077) gave error, haven't seen one that works
- Short description of error ---
  Cycles hair will only render when the hair particle system modifier on the emitter object is set to visible in the render (camera icon) AND in the viewport (eye icon).

In other words, it will only render if ParticleSystemModifier.show_render && ParticleSystemModifier.show_viewport evaluates to True.

Expected behavior is that the value of ParticleSystemModifier.show_viewport has no effect.

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

Create a blend file with particle system hair. Set to strand render, experimental, CPU, etc. (attached)
Go to modifiers (wrench) panel. Turn off viewport visibility by clicking the eye icon.
Hit F12 or Preferences panel > Render pane > Image or Render menu > Render Image. Only the default cube will render; no hair.
Turn viewport/render visibility on and off and observe.%%%
