User Warning

I get this user warning when I go to my themes/settings node.
If I refresh the page it goes away. What's up?

user warning: Duplicate entry 'themes/chameleon/marvin/marvin.info' for key 1 query: INSERT INTO system (name, owner, info, type, filename, status, throttle, bootstrap) VALUES ('marvin', '', 'a:13:{s:4:\"name\";s:6:\"Marvin\";s:11:\"description\";s:31:\"Boxy tabled theme in all grays.\";s:7:\"regions\";a:2:{s:4:\"left\";s:12:\"Left sidebar\";s:5:\"right\";s:13:\"Right sidebar\";}s:7:\"version\";s:4:\"6.10\";s:4:\"core\";s:3:\"6.x\";s:10:\"base theme\";s:9:\"chameleon\";s:7:\"project\";s:6:\"drupal\";s:9:\"datestamp\";s:10:\"1235596218\";s:8:\"features\";a:10:{i:0;s:20:\"comment_user_picture\";i:1;s:7:\"favicon\";i:2;s:7:\"mission\";i:3;s:4:\"logo\";i:4;s:4:\"name\";i:5;s:17:\"node_user_picture\";i:6;s:6:\"search\";i:7;s:6:\"slogan\";i:8;s:13:\"primary_links\";i:9;s:15:\"secondary_links\";}s:11:\"stylesheets\";a:1:{s:3:\"all\";a:1:{s:9:\"style.css\";s:33:\"themes/chameleon/marvin/style.css\";}}s:7:\"scripts\";a:1:{s:9:\"script.js\";s:33:\"themes/chameleon/marvin/script.js\";}s:10:\"screenshot\";s:38:\"themes/chameleon/marvin/screenshot.png\";s:3:\"php\";s:5:\"4.3.5\";}', 'theme', 'themes/chameleon/marvin/marvin.info', 0, 0, 0) in /nfs/c03/h04/mnt/58238/domains/jobprofilehelp.com/html/modules/system/system.module on line 821.
