I have quiz_question an diff enabled in a site, and I see these errors

Notice: Undefined index: #node en diff_node_view_alter() (línea 306 de diff/diff.module).
Notice: Trying to get property of non-object en diff_node_view_alter() (línea 307 de diff/diff.module).

I see that node_view in node.module ensures that the key exists in the the build array passed to drupal_alter, so maybe we should do the same before calling drupal_alter(array('node_view', 'entity_view'), ... in quiz_question_answering_form and QuizQuestionResponse::getFeedback.

Here's a patch that ensures that '#node' and '#language' are defined before calling drupal_alter.

Confirm the issue. Thanks for the patch! I think it can go rtbc directly.
