Browser: Google Chrome 18.0.1003.1 dev

Operating System: Mac OS X 10.7.2

When being loaded as a content script as part of a browser extension, jQuery triggers an error in Chrome 18, the current developer version of Chrome, and prevents code depending on jQuery from being executed.

The issue has been reported before by somebody else in the Chrome bug tracker: http://code.google.com/p/minimalist/issues/detail?id=171

To reproduce the issue, you can download this extension I created to demonstrate the problem: http://cl.ly/DPhc

The exact error varies across different versions, but leads to a failure of code dependent on jQuery in most cases (except 1.5).

1.7.1:

'''Uncaught TypeError: Cannot read property 'compareDocumentPosition' of null at line 4807''''

1.7:

Uncaught TypeError: Cannot read property 'firstChild' of null at line 1520

1.6.4:

Uncaught TypeError: Cannot read property 'firstChild' of null at line 1320

1.6.3:

Uncaught TypeError: Cannot read property 'firstChild' of null at line 1320

1.6.2:

Uncaught TypeError: Cannot read property 'firstChild' of null at line 1310

1.6.1:

Uncaught TypeError: Cannot read property 'firstChild' of null at line 1288

1.6:

Uncaught TypeError: Cannot call method 'appendChild' of null at line 1287

NOT WORKING

1.5:

Uncaught TypeError: Cannot read property 'compareDocumentPosition' of null at line 4148

(Simple code depending on jQuery can, however, still be executed with v1.5)

I am aware that this version of Chrome is a developer version that may contain bugs and does not have to necessarily be supported by jQuery. However, I would like to ask you to keep an eye on this in order to ensure full functionality of jQuery once Chrome 18 becomes beta or stable.
