The following commit has been merged in the webkit-1.1 branch:
commit 940b7ef4e0e437754198b410451c95f6901d1397

    [Qt] Revert "Implement ImageDecoderQt::clearFrameBufferCache()" from r52516.
    
    https://bugs.webkit.org/show_bug.cgi?id=32121
    
    The implementation appears to either run into an ASSERT
    or leak memory at runtime as the m_buffer, m_reader may
    already exist. The bug was reopened and we do have a plan now.
    
    * platform/graphics/qt/ImageDecoderQt.cpp:
    (WebCore::ImageDecoderQt::setData):
    (WebCore::ImageDecoderQt::clearFrameBufferCache):
    * platform/graphics/qt/ImageDecoderQt.h:
