the actual question is: what are you trying to achieve? a `SourceBuffer` is a `TextBuffer`, so you can pass any instance of the former to any method or signal of the latter. you cannot do the opposite, obviously, or you'd be violating the substitution principle of the type system. — ebassi, Mar 21 '14 at 13:39

You could just do

txtbuf.__class__ = GtkSourceBuffer

which should work as long as txtbuf actually is an instance of type GtkSourceBuffer.
