Undefined indexes and huge args-data in Zend\Log\Formatter\ExceptionHandler::format

A warning in advance: this can seriously crash your browser as it tries to write over 20.000 lines of code to the browser screen!

The notices the script produces:

Notice: Undefined index: file in D:\websites_assets\Zend-2.1.4dev\library\Zend\Log\Formatter\ExceptionHandler.php on line 43

Notice: Undefined index: line in D:\websites_assets\Zend-2.1.4dev\library\Zend\Log\Formatter\ExceptionHandler.php on line 44
