Because Qt does not know anything about Python references. It only has
the concept of ownership. The profile doesn't take ownership of the
interceptor (probably so you can use the same interceptor with
multiple profiles?), and Python doesn't know if Qt still needs the
interceptor - so you need to keep a reference it for it not to be
garbage collected.
