warning: strtr() [function.strtr]: The second argument is not an array. in /home/u4/testingtgf/html/modules/ubercart/uc_roles/uc_roles.module on line 256.

I'm seeing this error message when logged in as Admin. I'm using Beta 1 Drupal 5.5
The error doesn't show with member or a custom role "moderator"

Anyone seen this?
