The reason why the NullPointerException is thrown is because ICEpush adds a <style>...</style> resource that is not based on a URL:

<style type="text/css">
.ice-blockui-overlay {position: absolute;background-color: white;z-index: 28000;opacity: 0.22;filter: alpha(opacity = 22);}
.ice-status-indicator-overlay {position: absolute;background-color: white;z-index: 28000;opacity: 0.22;filter: alpha(opacity = 22);}
</style>
