To the best of my knowledge this is NOT a bug. The only reason why
this would happen is if the reader failed somehow but you would still
try to copy the buffer. Eg:

ImageReader ir;
ir.SetFileName( );
bool b = ir.Read()

assert( b == false ); // programmer should not go any further when
imagereader fails

Image& i = ir.GetImage();
char *b = new char[ ir.GetBufferLength() ]
i.GetBuffer( b )

Use the code ConvertToQImage.cxx and try to make it crash, with any
sample dataset you have. If you do, send me that dataset (you can use
anything from gdcmData).
