I haven't.

It's not.

--> there are *tons* of places with 0008|0000.
*mine* is at offset Off.: x(1c0a).

Actually, the problem is known for a long time
(see gdcmData/gdcm-MR-PHILIPS-16-Multi-Seq.README.txt )

The pb is not so terrible :
  The spurious tag is kept in the header, to show, at Print time, that 
there is a problem.
  It's useless, never used, and is not trouble maker.
  It's ignored at Write time; the written file is e-film readable.

Rewrite filein=gdcm-MR-PHILIPS-16-Multi-Seq.dcm fileout=dump.dcm
  produces a 'clean' dicom file.
