[RESOLVED] file_exists = true but require fails

[Derokorian]

I must be going crazy, but I have this piece of code

            $test_label_file = drupal_get_path('module', 'mj_compliance').'/states/nv_mmed/label_handlers/nv_test_result_label.inc';

        if ($test_result_id && file_exists($test_label_file)) {
            require_once $test_label_file;
            $obj = new nv_test_result_label();
            $obj->init($test_result_id);
            $output .= $obj->generateLabel();
        }

The problem is file_exists passes, but require fails. drupal_get_path returns a fully qualified path so I don't think it has to do with an include_path failure. Any idea what I'm missing?

No idea what the problem was, but it worked on the test server, so I did a git fetch and pull, and now its working locally too. Meanwhile, git fetch and git pull showed no changes happened so I have no clue....
