Global namespace collision in scriptdownloader.js

[arantius]

Originally: DevjaVu ticket 123

As reported originally on the -dev list:

There is a collision in the global chrome namespace in scriptdownloader.js on the function named PersistProgressListener.

Just another item in the long list of things about the code that can be cleaned up.

I'm not sure why this happens but if Console2 0.3.9.2, GreaseMonkey 0.8.20080609.0 and Cooliris Previes 2.6.4 are all installed at the same time, the following error appears in the error console on any window open or close:

Error: this.docShell is null Source file:
chrome://global/content/bindings/browser.xml

This occurs even on a brand new profile with just those three add-ons installed. If any of the three add-ons is disabled the error goes away so it's a combination of the three causing the problem. It doesn't appear to actually cause problems as far as I can tell, but something is obviously wrong.
