PHP5 class_exists() throws Exception without second parameter

[GoogleCodeExporter]

What versions and operating system are you using?

OS: Mac OS X 10.6.5
Firefox: 3.6.13
Firebug: 1.6.0
FirePHP Server Library: 0.3.2
FirePHP Extension: 0.5.0
Developer Companion: 0.0.0master1012210014

What is the problem?

On a PHP5 install of an app using FirePHP, I was getting a fatal uncaught 
exception caused by the class_exists() call on line 45:

if(!class_exists('FirePHP')) {
    require_once dirname(__FILE__) . DIRECTORY_SEPARATOR . 'FirePHP.class.php';
}

This can be fixed by adding the second parameter to class_exists which prevents 
the function from attempting to autoload the class:

if(!class_exists('FirePHP', FALSE)) {
    require_once dirname(__FILE__) . DIRECTORY_SEPARATOR . 'FirePHP.class.php';
}

I've attached the file with the fix in place. I can't see a problem with this 
fix since you explicitly require the file on the next line.

What steps will reproduce the problem?
1. Using Media Temple (dv) with PHP5
2. To see the error message, turn error reporting all the way up

I screwed this up two ways:

1. I posted under a friend's account. This account is the correct one.

2. I attached a file that had the second parameter set to TRUE instead of 
FALSE. I've attached an updated file.
