This is a bug. It should be:

public void set_forward_page_func (owned Hildon.WizardDialogPageFunc
page_func);

The data and destroy arguments are implicit in that.

Obviously when the 2 extra arguments go away here, they'll go away
in your code too. It will be:

set_forward_page_func(this.forward_page_function);

Note, that there should be no "data" argument in the
Hildon.WizardDialogPageFunc declaration either. The
C function has it, but it's used to pass the invocant
if passing method or the closure if you pass closure.
