Exactly what is not right there?

The Exception and Fatal Error work just fine. I am reporting this as a bug because error output has newlines in it but the HTML display does not reflect this format. I would expect the stack trace would be wrapped in <pre></pre> or even some sort of list so that it is readable in HTML output instead of all run together.

If you view it in a browser you see:

Stack trace:#0 [internal function]: Zend_Controller_Action->__call('helloAction',
Array) #1 /code/dev/php/Zend/Controller/Action.php(497):Portal_TrialController->helloAction() #2 /code/dev/php/Zend/Controller/Dispatcher/Standard.php(238):Zend_Controller_Action->dispatch('helloAction') #3 /code/dev/php/Zend/Controller/Front.php(920):Zend_Controller_Dispatcher_Standard->dispatch(Object(Zend_Controller_Request_Http), Object(Zend_Controller_Response_Http)) #4 /home/jjohnston/svn/dev/www/bootstrap.php(96): Zend_Controller_Front->dispatch() #5 /home/jjohnston/svn/dev/www/bootstrap.php(6): MW_Bootstrap::main() #6 {main}  thrown in <b>/code/dev/php/Zend/Controller/Action.php</b> on line

Notice the text is displayed in a long line without any visual separation. This is true of any thrown but not caught Exception, not Zend Framework specific.

The error message does add a <br /> before and after the error text.

It's expected. If you wish to print out exceptions in your website in pretty form, then you need to add <pre> tags or whatever around the place where the output happens. Normally you do catch every exception..and normally you do log errors and not output them on the webpage.
