CVS version checked out one week ago. Version string says 0.6.0. I
cannot read the image data either (BE/LE mismatch causes gdcm to seek
past the end of file).

Yes, the file contains both LE and BE parts. I tried to fix this in gdcm
early this year, but then I found that ITK DICOM reader has no problems
reading such files and switched to ITK. I'm just looking into what I
tried then. Basically I switched endianess whenever one of tags
feff|00e0 (already endian swapped) or fffe|e00d (end of swapped tags)
occurred. I'll try to fix gdcm this way and see wheter it helps.
