Error after pressing CTRL

I got an error after pressing the CTRL hotkey while creating some curves.

This issue was caused because the condition 'Grid Subdivision' (in 'Viewport Overlays' ) = 1 was not handled in script. There can be a proper fix to the problem after it's known how Blender makes use of the value of grid subdivision option (currently the option is disabled in Blender versions later than 2.8).

For now, I have put a work-around to avoid the exception.
