Summary: Crash with gdcm::Reader on a jpeg and try to Read twic

Initial Comment:
My problem is if i try to read for instance a jpeg file with a
gdcm::Reader().
if i try this code :
gdcm::Reader reader ;
reader.SetFileName( "c:\\toto.jpg" );
reader.Read();
readre.Read();


the program will crash ( not in gdcm v2.0.15 )
I identify the problem :
in gdcm v2.0.15 we close and set the Stream to NULL :

   Ifstream->close();
   delete Ifstream;
   Ifstream = NULL;
   Stream = NULL;

in gdcmv2.2.0 we do not set stream to NULL but we clear it so when we try a
second time to read it ( in preamble it crashes ).
