See attached .blend file to replicate:
1. Open test.blend
2. Run animation (Alt+A) to arbitrary point in the timeline (generating particles with dupli objects)
3. Render a frame from the animation
These steps should crash Blender (as of r35096)... gdb backtrace is below. Do note that if you change render display from New Window to either Fullscreen or Image Editor, the crash does not occur.
GDB backtrace:
