Since i'm new to this, i'm not sure if this is "user" error, or a bug. When I go to pages, then "user view" , then -operations/task handlers... I am getting this error on a blank screen.

Fatal error: __clone method called on non-object in /home2/xxxxxx/public_html/includes/common.inc on line 1685

Last night i went it (and i went through without getting the error), but I didn't complete a page before getting out of it... Now i can't manage to get in without the error. I uninstalled, cleared cache, etc. reinstalled... but it didn't change anything.
