Sometimes 'endian' order can cause this. Try '<3sII' and '>3sII' for
your formats to differentiate.
Also, if your file is not packed the way that 'struct' expects, you
might need to read the string and integers separately.
/Example:
>>> struct.Struct( '3s' ).size + struct.Struct( 'II' ).size
11
>>> struct.Struct( '3sII' ).size
12
