System Information
Operating system: Linux-5.0.0-15-generic-x86_64-with-debian-buster-sid 64 Bits
Graphics card: GeForce GTX 1060 6GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 418.56

Blender Version
Broken: version: 2.80 (sub 72), branch: blender2.7, commit date: 2019-05-26 22:34, hash: d525c76003
Worked: (optional)

Short description of error
When clicking on the 3D space with the mouse cursor after having selected the 3D cursor with the intent of positioning the 3D cursor , blender shut down.

Exact steps for others to reproduce the error

I had worked on a curve that I had just reset to object mode.
I went to click on 3D cursor to activate it
then I placed the mouse cursor in the left space to the curve to position the 3D cursor
I clicked on the space
Blender just shut down.
See file and screen shot attached

I did test with a new session of Blender,
selecting the 3D cursor
placing the mouse in the 3D space
The cursor got correctly placed at the point of clicking
Blender kept working
I could create a curve without problem

Could be related to the todo in DRW_cache_object_all_edges_get. It only works for meshes currently, but in that file it is called with a curve.
Alternatively we could also not draw the curve at all when is_flat_object_viewed_from_side is true in basic_cache_populate.

Here is a simpler file to reproduce the bug. It's simply a curve with the wireframe overlay enabled.
