Currently the GTK build is broken because the new test added along with bug 36128 need to be updated to match the code changed with the patch attached for bug 40009 (now a11y title and descriptions are prefixed by "AXTitle: " and "AXDescription: ", respectively).
It's a very simple patch, hence I'll be attaching the needed patch to updated the failing test and its expected results asap.
