phpMyAdmin :: Xdebug : Warning on mysql_free_result()

I've never experienced an occurrence of this error before. I don't recall any changing anything in php.ini or elsewhere which would have caused something different to happen like the error shown in the screen capture, however, i did modify some of the Xdebug output parameters per the Xdebug Documentation, as follows:

[XDebug]
zend_extension_ts="C:/PHP_5.2.3/ext/php_xdebug-2.0.0-5.2.2.dll"
;
;  

xdebug.collect_params=1
xdebug.collect_vars=On
xdebug.profiler_output_dir="C:\Apache2.2\htdocs\tmpXDebug";

xdebug.manual_url="http://php.net/"
xdebug.remote_host="localhost"

;
;

Other than this modification, I can't think of any reason why this error would have occurred.
