Ok, after reading the error I have a better understanding and some positive steps in reproducing the problem.
The error actually appears to be coming from the G4 media player for "The MMO Report". I consistently get the error when loading the home page when the player is present, but not when loading an individual page post w/o the player. The player can time out from their media server and it looks like it can leave a tracking script pending. Not sure what could be done about that though. I can send along the error if you have contact w/ the folks at G4. Maybe they can at least change it to fail more gracefully.
That being said, there are still a few ads as well that cause issue. If I notice any ones in particular I'll snag the URL and send it along
