It was fixed in CVS a while ago. The code in CVS reads as below instead
of what you have. Please update Code/IO and you shouldn't have this
issue.

  if( strcmp( this->GetOutput()->GetNameOfClass(), "VectorImage" ) ==
0 ) \
     { \
     ConvertPixelBuffer<                                 \
      type,                                             \
      OutputImagePixelType,                             \
      ConvertPixelTraits                                \
      >                                                 \
      ::ConvertVectorImage(                             \
        static_cast<type*>(inputData),                  \
        m_ImageIO->GetNumberOfComponents(),             \
        outputData,                                     \
        numberOfPixels);                                \
     } \
