Broken: 2.71 (release candidate 2)
Short description of error
Blender 2.71 (rc2) crashes when a UV Sphere is added to a existent project in Edit Mode.
Exact steps for others to reproduce the error
Using the attached file, select the figure (stickman), go to Edit Mode and add a UV Sphere. After executing these steps, Blender stops responding and it's necessary to force quit and reopen.
It seems that's something to do with the modifiers (in the attached file, I'm using Mirror, Skin and Sub-surf). One or more of them are causing the crash when the UV Sphere is added. If I create a new project with no modifiers, I'm able to add UV Sphere.
