I just check if it is an ApplicationRuntimeException in my method (in my
engine class) : 
    protected void activateExceptionPage(IRequestCycle iRequestCycle,
ResponseOutputStream responseOutputStream,
                                         Throwable throwable) throws
ServletException {
        ExceptionRethrower exceptionRethrower = (ExceptionRethrower)
                getBean("exceptionRethrower");
        exceptionRethrower.checkForRethrow(throwable);

            //If we get here, no exceptions was rethrown
            if(throwable instanceof ApplicationRuntimeException){
                    ApplicationRuntimeException apr = 
(ApplicationRuntimeException)
throwable;
                    log.error("Error message   : "+apr.getMessage());
                    log.error("Error component : "+apr.getComponent());
                    log.error("Error location  : "+apr.getLocation());
            }
            log.warn("\"Client-side\" exception occured:", throwable);

        super.activateExceptionPage(iRequestCycle, responseOutputStream,
throwable);
    }


Instead of logging it as done in method above, you could put the same
information into the email. 
I guess it might even be possible to render the framework exception-page
and put the resulting html into an email as well, that would be even
better...
