Exact steps for others to reproduce the error
Open blender, open my file then crash when Rendering (F12)

Event Timeline

I'm not sure but it can be related to track to constraint on the main camera. When I remove this constraint, it doesn't crash for me

George Vogiatzis (Gvgeo) triaged this task as Confirmed, Medium priority.

From build_object function, &object->id is NULL

I have a similar problem where camera is parented to and empty which is parented to an object. See attached file, it crashes on render too:


Worked yesterday in a1ad71304c2d

@Marcin Twarowski (Tvaroog) Same error.
Crashes get_cow_id too. Again &object->id is NULL
