Creating a duplicate cone mesh object and then typing in its coordinates after placement crashes blender

Description: Blender crashes upon creation of a duplicate (or duplicate-linked) cone whose location is manually modified post creation.

Minimal steps to reproduce:

  1. Start with a new scene (delete the starting cube)
  2. Create a cone at the origin (default size)
  3. Click on Duplicate or Duplicate Linked (both have the issue), positioning the new cone just below the original along the Z axis (alignment isn't critical here) and left clicking to place

Comment: Now, in order to fully align the newly created and manually placed cone along the Z axis, we want to change its X and Y coordinates manually to 0.0

  1. With the new duplicate cone still selected, we click on Vector/X in the left panel to manually enter the X coordinate of its position.
  2. Type in the value 0 for the X coordinate.
  3. Upon pressing Enter to confirm the value, Blender crashes.

Trying to use a NULL pointer somehow after undo/redo implied by redoing an operator I think?

Cannot reproduce the crash anymore with current blender2.8 branch, so think we can consider that issue fixed. :)
