[Project_owners] Problem with JSLib on trunk (Gecko 1.9.1)

[Pete Collins]

There is a new File global script object now?

Ideally I think jsLib should go in the direction of putting all it's 
objects behind a jslib namespace.

This will however break backwards compatibility and that is something I 
don't want do.

You might need to do this:

  File = null;
  include(jslib_file);

  var f = new File(du.getPrefsDir());

Right here is where the global object is defined:

  
http://mxr.mozilla.org/mozilla-central/source/dom/src/base/nsDOMClassInfo.cpp#3447

I think it should be called "DOMFile" and *not* "File".
