Problem description

I wanted to make a full circle in a sketch but the command "create circle from center and radius" is not available in Linkmerge (it is in linkstable) so I tried to make it with command "create arc by center" with coincident first and last points.

I have made following steps:

1. Start FreeCAD
2. New Document
3. Start Part Design
4. New Part
5. New Body in the Part
6. Select XY plane and start new sketch
7. Create arc by center
8. Set center, first point,
   When I select last point=first point FC crash leaving following error messages in the bash console:

Beside fixing this bug I would like to have also the missing commands for circle creation.
