Call-time pass-by-reference has been deprecated

I seem to have come across this issue again. After activating the module on my Drupal 5.1 installation ( MySQL database 4.1.14 / PHP 4.4.4 / Apache/2.0.46 ), I get the following message:

Warning: Call-time pass-by-reference has been deprecated - argument passed by value; If you would like to pass it by reference, modify the declaration of [runtime function name](). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file. However, future versions may not support this any longer. in /home/craig/community20.ca/beta/modules/util/util.module on line 78

in my settings.php, I've set the following to display errors and warnings:

ini_set('display_errors',	'On');
ini_set('error_reporting',	E_ALL);

Also note, that when I try to disable "Collapse all fieldsets on the module enabling page" on the Utility module settings page, I get the proper message telling it has saved the changes, but the checkbox is checked again even though it does not collapse the fieldset on the module page.

This is a list of active modules I have incase it helps in tracking down the culprit.
