           Summary: Don't attempt to destroy decoded frame if a
                    BitmapImage doesn't have encoded raw data.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: yongjun_zhang at apple.com


With BitmapImage::create(PassNativeImagePtr, ImageObserver*), a BitmapImage could be created by passing a native image.  If this image is added to memory cache, we shouldn't attempt to destroy its decoded frames since there is no encoded raw data and we won't be able to reconstruct the image again.
