Tested as separate script, this gives segfault too:


from gi.repository import Gtk
from gi.repository import WebKit2

class HTMLActivity(Gtk.Window):
    def __init__(self):
        Gtk.Window.__init__(self)

        self._web_view = WebKit2.WebView()
        self.add(self._web_view)
        self._web_view.show()

html_activity = HTMLActivity()
html_activity.connect("delete-event", Gtk.main_quit)
html_activity.show()
Gtk.main()
