icecore:navigationNotifier fails in IE11:
the counter is not increased, and a server error occurs each time when navigating back and forward in the browser;
not an issue in IE7/8/9/10, FF34 or Chrome42; not an issue on IF4 trunk rev. 44662.

After restarting Tomcat a few times the server error stopped occurring when testing locally (it still occurs when testing remotely), but the counter still fails to increase.
