As Tomeu suggested, could you check the presence of inherited methods? I
would suggest you to also check the ancestors tree of FileChooserDialog
(FileChooserDialog.__bases__) in both cases (when libchamplain is
imported before and when it is not), and look for differences between
the two.

By the way, is there currently a way to make overrides behave
differently for Gtk-2.0 and Gtk-3.0 for instance? Could be useful for
apps not willing to move to Gtk-3.0 yet (but I don't know whether this
seems acceptable from Gtk maintainers' point of view or not), or some
other library whose API is going to be broken at some point.
