Short description of error
Deleted default cube reappears if I make a mesh circle and change the number of vertices. Or, if I modify the default cube and then create a circle, when I adjust the number of verts in the operator properties panel, blender immediately crashes.
Exact steps for others to reproduce the error
(I Have in user preferences: 'enter edit mode' checked)
(I have 'default' screen layout on main screen and just a node editor in a secondary window on another monitor.)
Delete the default cube.
Create a mesh circle.
Use the operator properties panel to change the number of vertices.
Default cube should reappear.
