Bug#771150: Webkit browser crashs while accessing Tumblr login page.

[Yoshizumi Endo]

Package: gir1.2-webkit-3.0
Version: 2.4.7-2

When I access the Tumblr login page with a Webkit browser
and enter some letters on the login entry,
the browser crashs with segmentation fault.
I am using Debian GNU/Linux jessie.

#!/usr/bin/env python
 
from gi.repository import Gtk, GObject, WebKit

class WebKitTest(Gtk.Window):

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

        self.connect("delete-event", Gtk.main_quit)
        self.resize(640, 480)

        w = WebKit.WebView()
        w.load_uri("https://www.tumblr.com/login")

        sw = Gtk.ScrolledWindow()
        sw.add(w)

        self.add(sw)
        self.show_all()
 
if __name__ == "__main__":
    w = WebKitTest()
    Gtk.main()
