          Platform: Macintosh PowerPC
               URL: http://test.halltank.com/
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Critical

         Component: Web Inspector
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kevin at rhubarbproductions.com


Open a new tab and go to the above link. Open the Web Inspector (I usually do it via Command-Option-I). Then right-click on the text in the Welcome paragraph and Inspect Element. Now use Command-W to close the tab. Every time I do these steps, Webkit crashes.
