--- Comment #1 from Michael Catanzaro <mcatanzaro at redhat.com> ---
So the problem here is:

 * Gesture begins
 * Tab is closed, web view is destroyed
 * Gesture finishes, WebPageProxy::didEndViewGesture calls WebPageProxy::protectedPageClient
 * PageClient::ref attempts to g_object_ref() the destroyed web view
 * object_ref: assertion '!object_already_finalized' failed
