taxonomy.module on line 70 error message

Hi all

Been trying to figure this wried error message everytime a user uploads a file. I did ask in the drupal forums but no one seems to know what to do.

when a user uploads a flash game on the site, it has a error message above of it:

/home/content/X/X/X/'database username'/html/modules/taxonomy/taxonomy.module on line 70.

it now displays the error message twice in one page.
I did try to re-upload the taxonomy module with a fresh new one but no signs of the error message going away. Can other modules like views or CCK can cause this error?

The site runs fine and you can browse the site fine and play games without any issues. And when you do click on a flash game, that taxonomy error message doesnt appear.
My current drupal install is: version 6.13

any help would be great,
