Cannot print messages with custom interpolators

[ldynia]

I have django app that is using {{ }} for printing content in the html templates files. The common solution for angular to play with django is to override angular interpolators e.g:

  $interpolateProvider.startSymbol('{[');
  $interpolateProvider.endSymbol(']}');

Doing so I lost ability of print messages in cg-busy directive. Any idea how to fix it ?
