           Summary: ImageDocuments erroneously trigger beforeload events
                    for the main resource
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Keywords: InRadar
          Severity: Normal
          Priority: P2
         Component: Page Loading
        AssignedTo: webkit-unassigned at lists.webkit.org

When an ImageDocument is loading, it creates an <img> tag, which triggers a beforeload event. However, the event corresponds to the main resource, and can cause a crash if the event is handled and preventDefault() is called.
