security - Unsafe JavaScript attempt to access frame in Google Chrome

Our web application (based on HTML5, SVG & JS) runs fine in all the browsers except Google Chrome.

In Google Chrome, the normal javascript events run fine, however, all the javascript events attached to the iFrame are not executed. We get the error in the console:

Unsafe JavaScript attempt to access frame

At the moment, the application is locally hosted and this problem cropped up during inhouse testing.

Googling this brings up lots of posts but none suggests any concrete solution. Any suggestions?

As an additional security measure, Chrome treats every "file" path as its own origin rather than treating the entire "file" scheme as a single origin (which is what other browsers do). This behavior applies only to "file" URLs and you can force Chrome to revert to a single local origin (like other browsers) by passing the --allow-file-access-from-files switch at startup.

You can find more information on the risks associated with local origins described here: http://blog.chromium.org/2008/12/security-in-depth-local-web-pages.html
