           Summary: Webkit crashes on site access
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
               URL: http://www.trf5.jus.br/
        OS/Version: Mac OS X 10.7
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: New Bugs
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: bernhard at icsi.berkeley.edu


Steps to reproduce: open http://www.trf5.jus.br/

Results:  Accessing http://www.trf5.jus.br/ reloads the website a couple of times and then crashes the webkit nighly build (WebKit r109005).

Expected result: Webkit displaying the site

Build: WebKit r109005 on Max OS x 10.7.3

This seems to be a longer standing bug - e.g. chrome crashes completely and webkit on safari 5.1.3 also crashes.
