No output in Firebug when _redirect was called - zend-framework

Question

The code (taken from SO):
// create the logger and log writer
$writer = new Zend_Log_Writer_Firebug();
$logger = new Zend_Log($writer);
// get the wildfire channel
$channel = Zend_Wildfire_Channel_HttpHeaders::getInstance();
// create and set the HTTP response
$response = new Zend_Controller_Response_Http();
$channel->setResponse($response);
// create and set the HTTP request
$channel->setRequest(new Zend_Controller_Request_Http());
// record log messages
$logger->info('info message');
$logger->warn('warning message');
$logger->err('error message');
// insert the wildfire headers into the HTTP response
$channel->flush();
// send the HTTP response headers
$response->sendHeaders();
$this->_redirect('/login/success');
Apparently, all the messages won't appear if I use _redirect(), however, if I use something like
$this->getResponse()->setHeader('Refresh', '0; URL=/login/success');
it will work. So my question is:
What should I do to make sure the messages will appear in my Firebug Console (using _redirect())?
Update 1:
In the Net tab, I can see the messages are in the HEADER, but it's not appearing in my Firebug

Update 2:
Apparently it's a bug, confirmed in FirePHP Official Forum. I'll wait untill there's a real fix before I answer this question.
Thanks for the detailed test case.
This is a bug in FirePHP Companion.
Working on a fix. Will let you know
when done (ETA Friday).
Thanks! Christoph

Answer 1

Does enabling the "Persist" option in the Firebug Console tab help?

Answer 2

This is the official answer from the author himself:
I have good and bad news. Logging during redirects works now for FirePHP 1.0 + FirePHP Companion. It will not work for the native Zend Framework implementation until early next year.
To get a working solution, please upgrade to FirePHP 1.0: http://upgrade.firephp.org/
Also see: http://www.christophdorn.com/Blog/2010/11/29/firephp-1-0-in-5-steps/
Instructions for logging during redirects:
http://reference.developercompanion.com/#/Tools/FirePHPCompanion/FAQ/#Redirect Messages
I would suggest using the FirePHP 1.0 library in addition to or instead of the ZF components. This will be much improved early next year.
Please let me know if you get this working.
