S 0029|263d lg : x(7088) 28808 [SQ]  (starts at offset  x(1b4a) 6986 )

   there is a 'true length SQItem'
    fffe|e000 lg : x(7080) 28800 [UL]  (starts at offset  x(1b52) 6994 )
 
      inside, a 'true length' Sequence :

			 fffe|e000 lg : x(2c) 44  [UL] (starts at offset x(1be2) 7138)
	      
         that contains ( at offset  x(1c02) 7170) the *impossible* tag :		
          fffe|0000 lg : x(44c55) 281685   [UL] (starts at offset x(1c02)7170
          its 'length' is  x(44c55) 281685 ?!?
			It's taken as a 'group length' (element number = 0x0000),
         (run PrintFile ans have a look at the output :
         PrintFile level=2 filename= ... )
         gdcm forces its value to 4, and the parsing goes on, successfully.
