           Summary: BitmapImage::frameIsCompleteAtIndex() must return
                    false if ImageDecoder is not initialized.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Images
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: luxtella at company100.net


The current code fortunately has worked so far because only BitmapImage::startAnimation calls frameIsCompleteAtIndex, and startAnimation cannot call frameIsCompleteAtIndex if ImageDecoder is not yet initialized. startAnimation returns at the first line becase shouldAnimate() always return false in this case.

        if (m_frameTimer || !shouldAnimate() || frameCount() <= 1)
            return;

This change is needed because parallel image decoders call BitmapImage::frameIsCompleteAtIndex in other places too.
