"Cannot Modify Header" error on album creation/cap

I have Gallery installed and working great in my Geeklog site, but when I add an album or try editing all captions I get the following errors;

Warning : Cannot modify header information - headers already sent by (output started at /usr/local/www/virtual1/66/175/18/245/html/clockworkrocks/gallery/classes/geeklog/UserDB.php:41) in /usr/local/www/virtual1/66/175/18/245/html/clockworkrocks/gallery/do_command.php on line 102

and

Warning : Cannot modify header information - headers already sent by (output started at /usr/local/www/virtual1/66/175/18/245/html/clockworkrocks/gallery/classes/geeklog/UserDB.php:41) in /usr/local/www/virtual1/66/175/18/245/html/clockworkrocks/gallery/captionator.php on line 9

The albums do get created and the captions do get updated, but this error appears. Any suggestions?
