In chrome, the loader for SVN history doesn't work.
In Firefox, you get this warning:
Use of Document.load() is deprecated. To upgrade your code, use the DOM XMLHttpRequest object. For more help https://developer.mozilla.org/en/XMLHttpRequest
My guess would be that Chrome doesn't suppor the deprecated function. The code should be updated accordingly.
Okay, I'll look into this for the pending 1.0 release.
