I have this exact same problem in Gaupol, where I have a notebook, which
contains scrolled windows and inside tree views. I have looked for the
cause, but haven't found it. The vague warning doesn't tell which widget
is the problem and I haven't found any solution via calling the implied
gtk_widget
Anyone?
