G_IS_OBJECT, and all the macros around G_TYPE_CHECK_INSTANCE_TYPE,
assume that you're either passing NULL, or that you're passing a valid
GTypeInstance pointer, as the type system will need to access the
fields of that particular structure. if you pass something that is
*not* a pointer to a GTypeInstance you'll likely either to get a
segmentation fault, or to read some garbage from memory.
