One update on this issue, the login function on this site is also bugged with chrome, sometimes it does not show that i'm logged it, yet when i click on another link, i am logged in again. Not sure if this problem is on chrome only though.
My theory is that the bad script is from one of the google ads. The same ads don't always appear on every page, so that would explain why the problem seems to happen at random. And these ads are targeted based on the user's geographical location. Perhaps these scripted ads don't get served to US users. And maybe that's why the Head-Fi/Huddler team can't track this thing down.
I've had every single one of these issues running Chrome on Windows 7 (64-bit desktop and 32-bit netbook). The most frequent issues are the login problem mentioned and that hitting reply doesn't do anything but jump me to the top of the page. It's really frustrating and made me switch back to Firefox.
