I create an object with Hair particle system on it and with a number of hairs = 0.
Then I enter into "Particle Mode" and when I change Edit mode to "Point edit mode" (see the attached image), Blender crash.
This does not happen when I select "Tip edit mode" or when my object has a number of hairs >= 1.

This is the console error I receive:

1071 Segmentation fault: 11 /Applications/[3D]/Blender/blender-2.65\ Official/blender.app/Contents/MacOS/blender
logout

I found this issue in Blender's official revisions r52859 (2.65) and r51026 (2.64) OSX 64bit Builds.

I have attached a .blend file so you can try the bug. You must only click on "Point edit mode" (see the attached image as reference) and the program will crash.

I'm working on an 2.66 GHz Quad-Core Intel Xeon with NVIDIA GeForce GT 120.
OSX Lion 10.7.5
