           Summary: REGRESSION: Crash loading script on myspace.com profile
                    page after logging in
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: NEW
          Keywords: NeedsReduction, Regression
          Severity: Normal
          Priority: P1
         Component: Page Loading
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: ddkilzer at kilzer.net


Summary:

After logging into myspace.com, viewing a profile page causes WebKit r18075 to
crash while loading a JavaScript source file on the page.

Steps to reproduce:

1. Log in to (or create an account on) http://www.myspace.com/.  (NOTE: I've
been getting errors logging into myspace.com this morning.  Ignore them--you
are logged in--and continue to Step 2.)
2. Access a profile page like http://www.myspace.com/tom.

Expected results:

The profile page should load without crashing.

Actual results:

The profile page crashes WebKit.

Workarounds:

N/A

Notes:

Regression from Safari 2.0.4 (419.3) on Mac OS X 10.4.8 (8L127).  Reproduced on
a locally-built debug build of WebKit r18075 as well as WebKit nightly r18068
(which has a shorter/less-detailed stack trace).
