HI, my forum is version 6.2 and I have also been able to duplicate the error:
Fatal error: Unsupported operand types in /home/soccerny/public_html/drup/includes/common.inc on line 1265

It occurs after the user hits "save" right after the "preview" comment, when responding to a post in the forums.

The post however, ends up in the forum. However the user is unable to "delete" forum posts only edit? Is this a permissions issue?

Help! :)

Thanks

first thing you should so is update your core to the most recent release.

If that doesn't fix the problem start reading these related threads = http://drupal.org/search/node/Unsupported+operand+types

Issue solved, error persisted after upgrade....

When I updated my core I now get this message:
Fatal error: Unsupported operand types in /home/mysite/public_html/drup/includes/common.inc on line 1369

I turned off the module comment_notify thanks to the forums here and the issue is resolved...thanks!
