            Bug ID: 186467
           Summary: Loading cnn.com in MiniBrowser hits Structure::dump()
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: simon.fraser at apple.com

It seems really weird that we'd hit Structure::dump() when just loading a web page. I have no extra logging enabled, and am not web inspecting.
