You are seeing side-effect of this commit: https://github.com/angular/angular.js/commit/9532234bf1c408af9a6fd2c4743fdb585b920531 that aims at addressing some security hazards.

This commit introduced a non-backward compatible change for urls starting with file:// (it was subsequently relaxed in https://github.com/angular/angular.js/commit/7b236b29aa3a6f6dfe722815e0a2667d9b7f0899

I assume that you are using one of 1.0.5 or 1.1.3 AngularJS versions. If so you can re-enable support for the file:// URLs by configuring $compileProvider like so:

angular.module('myModule', [], function ($compileProvider) {

  $compileProvider.urlSanitizationWhitelist(/^\s*(https?|ftp|mailto|file):/);

});

Or in Angular 1.2.8 and above:

angular.module('myModule', [], function ($compileProvider) {

  $compileProvider.aHrefSanitizationWhitelist(/^\s*(https?|ftp|mailto|file):/);

});
