Description of problem:
Bringing up the RHQ GUI in IE8 produces the following errors:
Message: Exception thrown and not caught
Line: 185
Char: 34
Code: 0
URI: https://<machine name>/a4j/g/3_3_3.CR1org/richfaces/renderkit/html/scripts/jquery/jquery.js.xhtml

Version-Release number of selected component (if applicable):
3.0.0


How reproducible:
Every time

Steps to Reproduce:
1)  In IE8, go to the rhq URL (will vary depending on the machine)
2)  Enter the username/password for rhq
3)  The error should happen right away b/c it seems to be tied to the dashboard tab.  
4)  Look at the very bottom left hand corner of the web browser.
5)  You should see a yellow warning triangle with the message “Done, but with errors on the page”
6)  Click (double click) on the yellow warning triangle.
 
Actual results:
Message: Exception thrown and not caught
Line: 185
Char: 34
Code: 0
URI: https://<machine name>/a4j/g/3_3_3.CR1org/richfaces/renderkit/html/scripts/jquery/jquery.js.xhtml


Message: Object doesn't support this property or method
Line: 46
Char: 2
Code: 0
URI: https://<machine name>/js/pngfix.js

Expected results:
Webpage should not have errors.  Should say Done.

Additional info:
It looks like this error is tied into code that was supposed to fix images with png extensions for IE7 or early versions, but somehow breaks in IE8.
