This TIFF looks very interesting. It looks like they took three normal channels and stored one of them as the regular channel, and two of them as extra sample channels. The two extra channels are not marked as alpha channels. Did the TIFF file get any smaller when you removed bands? If you don't create a "subset" image are there five extra sample channels?

I would be interested to get my hands on one of these odd TIFF files in order to see how GraphicsMagick (http://www.graphicsmagick.org/) deals with it.

If GraphicsMagick can read it properly, it can certainly output normal RGB TIFFs based on what it read.
