Hi, Luca.
Do you have the problem on any dat set (I mean : does it hang always on 
the 2-d image, or is it on a given image? )
Can you display all your images with vtkgdcmReader ? or at least look at 
the header with PrintFile ?
If one of them doesn't work with 'low level tools', could you send me a 
sample?

A few weeks ago, I had to face images with a supposed to be 'bugged 
header' -within a 'private' Sequence, a delimitor had a wrong length -, 
and gdcm was unable to parse the header...
