           Summary: Recent JS behavior changes breaks NASA homepage.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh PowerPC
               URL: http://www.nasa.gov/home/index.html
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jon at jonshier.com


It looks like a recent change in JS behavior has broken the main story section
on the NASA homepage. The page briefly beachballs as the system deals with the
JS errors encountered and then the inspector shows the errors increasing by
several hundred when mousing over the story sections. All of them are similar
to this:

TypeError: Result of expression 'element' [undefined] is not an object. 
TypeError: Result of expression 'expression.strip' [undefined] is not a
function.
TypeError: Result of expression 't' [undefined] is not an object.
TypeError: Result of expression 'this.extractScripts' [undefined] is not a
function.
TypeError: Result of expression 't' [undefined] is not an object.
TypeError: Result of expression 'this.extractScripts' [undefined] is not a
function.
TypeError: Result of expression 'this.callback' [undefined] is not a function.

I'll add more information once I'm able to go through the nightlies and find
when exactly this started.
