While building 1.10.8, the open build server raises an error from the build root policy checker:

I: Program returns random data in a function
E: clutter no-return-in-nonvoid-function test-touch-events.c:78

The function in question is:
static gboolean
draw_touches (ClutterCairoTexture *canvas,
              cairo_t             *cr)
{
  g_slist_foreach (events, (GFunc) draw_touch, cr);
}
