        * gtk/gtkicontheme.c: When changing the icon theme, defer
        the resetting of rc styles to an idle, so that it does
        not happen e.g during expose handling (which is problematic,
        since some widgets, like the toolbar, are changing the
        hierarchy in response to style changes).  (#300539, reported
        by many people, analyzed by Owen Taylor)
