$this->hasHostInfo=!strncasecmp($pattern,'http://',7) || !strncasecmp($pattern,'https://',8);

This error occurs if your config is corrupt. Check your config in:

['components']['urlManager']['rules']

If you have set an empty array at this position, you'll get the reported error.

return array(
    'components'    => array(
        'urlManager'   => array(
                'rules' => array(
                    '<controller:\w+>/<id:\d+>'
                        => '<controller>/view', // fine

                    array(), // Won't work!!
                    '<controller:\w+>/<id:\d+>'
                        => array(), // Won't work!!
                ),
        )
    )
)

Please check the documentation and update to the most recent version 1.1.15 which is an important security update.
