It would be interesting to know which system is producing this kind of buggy DICOM file. Full thread: https://groups.google.com/d/msg/comp.protocols.dicom/SkU5_OUSDxE/PZfjvdU3EwAJ It contains a command line (using DCMTK) to cleanup this file, before passing it to stricter implementation (GDCM <= 2.6.3).
