I have the start of a patch :

diff --git a/Modules/IO/NIFTI/src/itkNiftiImageIO.cxx

+    }
+
   // We don't need the image anymore
   nifti_image_free(this->m_NiftiImage);
   this->m_NiftiImage = 0;

"It works for me" but I've only looked at one image on one machine and I
don't really know the implications of setting this member variable.
