System Information
Windows 10 & Ubuntu 18.04
nvidia gtx 1050ti

Blender Version
Broken: 2.79 2461be1
Worked: 2.79 f28aec1

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.

This doesnt happen if you use Global Undo, so only the combination of Enter Editmode ON and Global Undo OFF

Still didnt find time to study UNDO in more depth, so passing this on to @campbellbarton...
