Yes. In the UI we have a couple of LinkButton's that are not meant to open any link in any browser. I added a dummy callback (on_activate_link) and I connected it with those buttons to the activate-link signal. According to the doc, if I define a handler for the activate-signal and return True, http://developer.gnome.org/gtk3/stable/GtkLinkButton.html#GtkLinkButton-activate-link, the default handler gtk_show_uri will not be called, but in practice it's called. I would guess this is a bug... the warning complains about the "uri" property being invalid (which is intended, since we don't want any link to be opened in any browser).
