ok, this one should be fixed as well now. We did not reset the status of
the GLObject when deleting them and since we reuse ids a newly created
GLObject was thought to be valid and never initialized [1].

[1] we did reset the status when creating the GLObject, but since that
happens in the loader aspect it has no effect on the render aspect.
