I think I'll have to really support this one. No this is NOT a valid 
DICOM file. Your meta header specify that the dataset is encoded in Big 
Endian:

D 0002|0010 [UI] 
[Transfer Syntax UID] [1.2.840.10008.1.2.2 ]  ==>       [Explicit VR - 
Big Endian]


But your dataset was encoded in little endian. If you have a lot of 
those file, then you need to open them with an hex editor and change the 
string

1.2.840.10008.1.2.2 into 1.2.840.10008.1.2.1

Then try running ITK again on your file.
