Blender Version
Broken: 2.69 release & hash:
19f7f9aShort description of error
Changing particles type from emitter to hair leads Blender to crash if the same particle system is combed in another instance.
Exact steps for others to reproduce the error
Hair_selection_crash.blend
Steps:
Add a cube.
Give it a particle system.
Comb it.
Duplicate the cube.
Go to the particle system of any cube.
Click on Free Edit.
You have now a combed cube and a non-combed cube.
They use the same particle system.
Crash: Switch type back to hair.

Crash seems to be related to threading, I couldn't redo the bug with
-t 1passed to blender.@ideasman42, it's totally unrelated on the threading since i can easily redo the issue with 2.70-RC1 with
-t 1argument and the same exact bug happens in 2.69 release.Added subscriber: @Sergey

Probably we will leave it this way until particles get refactored for Goosberry. Changing this fundamental feature just for one bug would invalidate lots of documentation and tutorials (and cause more reports in return), so it's probably acceptable for the time being.
