We are calling WebKitGTK functions only on the main thread.
But we are calling other GTK functions on other threads.
One problem that we figured out is that gdk windows now share their
impl_window, so if there are parallel calls to invalidate rectangle
on children of the same window, they mess up the update_area of the
impl_window. That seems to be the problem in the backtrace that I
It loks like using a webkitwebview widget forces all the GTK calls on
any widget in the same window to be on the main thread.
