Worked: (optional)
Description: Crashes upon creation of a 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)
Comment: Now in order to fully align the newly linked cone we want to start by changing its X and Y coordinates manually to 0.0.
4) 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.
5) Type in the value 0 for the X coordinate.
6) Upon pressing Enter to confirm the value, Blender crashes.
