[Gdcm2] GDCM cannot get rescale intercept/slope/type from nested objects with undefined length

[<k3...@fr...>]

Hi,

I am trying to read a DICOM series (multi-echo series from Philips) but I need to check some DICOM tags first:
- 0028,1052: rescale intercept
- 0028,1053: rescale slope
- 0028,1054: rescale type

Unfortunately GDCM is not able to find that tags through ITKs API (gdcmIO->GetMetaDataDictionary()), but when I use gdcmdump to search for DICOM tags manually I am able to find the tags but in nested objects with "undefined length":

(2001,1068) ?? (SQ) (Sequence with undefined length)          # u/l,1 ?LinearModalityGLTrafo
      (fffe,e000) na (Item with undefined length)
        (0028,1052) ?? (DS) [-12095]                              # 6,1 Rescale Intercept
        (0028,1053) ?? (DS) [5.90720390720390]                    # 16,1 Rescale Slope
        (0028,1054) ?? (LO) [normalized]                          # 10,1 Rescale Type
        (2001,0010) ?? (LO) [Philips Imaging DD 001]              # 22,1 Private Creator
        (2001,1077) ?? (CS) [LINEARMODALITY]                      # 14,1 GL TrafoType
        (2001,10c1) ?? (LO) [LinearModalityGLTrafo ]              # 22,1 Nested Object Type Name
      (fffe,e00d)
(fffe,e0dd)

Is there a way to fix that? Did you ever see that kind of nested objects? Is there a configuration on the Philips workstation to avoid that kind of nested objects?
Thanks.
