Short description of error
Blender crashes when the particle system is turned off in particle editing mode. The specific configuration of particle systems cause this error, I tried to create a simpler example, but without success.

Exact steps for others to reproduce the error
hairtest.blend

Open file.
Switch to particle edit mode
Disable first particle system in modifier stack - Blender shuts down immediately
