libraries/Router.php Bug

[eluser]Unknown[/eluser]
Hello,

I found that if we try to visit any CI controller with spaces in the URL (i.e. http://www.example.com/abc/ ), it will give a notice error in libraries/Router.php file on Lines 201, 207, and 210.

The problem was in the _validate_request() method in CI_Router class. I added the following code to the beginning of that function to fix the problem:

Code:

/**
* Bug Fix
*/
        if (count($segments) < 1)
        {
            $segments = array('');
        }
/**
* End
*/

Is this a valid bug in the CI_Router class?
