Executing bpy.data.objects["Empty"].data = None where Empty is an empty object causes a segmentation fault. This is caused by the following check in rna_Object_data_set:

if ((id->tag & LIB_TAG_NO_MAIN) != (ob->id.tag & LIB_TAG_NO_MAIN))

Which was introduced in blender/blender@34d676. In particular, we are dereferencing the variable id which is null in this case.
