Got it !!
I simply needed to give the name of my app instead of silly "ie7support" in the code below:
angular.module('ie7support', []).config(function($sceProvider) {
// Completely disable SCE to support IE7.
$sceProvider.enabled(false);
});
Found thanks to a deeper look at this article: http://docs.angularjs.org/api/ng.$sce
Hope it can help some of you !
