           Summary: REGRESSION: Repro crash when a second background image
                    is animated
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: NEW
          Keywords: Regression, NeedsRadar
          Severity: Major
          Priority: P1
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mitz at webkit.org


I noticed that RenderObject registers as a client of all its background images
but unregisters only from the first one. This makes it leak, and in the case of
an animated image, also crash (since the image tries to notified the deleted
object of changes). Test case coming up.
