Ah, and I think I know why it only failed with 3-d textures (would have
failed with 1D and 4D too, actually).  The PyOpenGL wrapper was only
setting unpack alignment for the 2D case.  It actually does a lot of
configuration to make the operation "natural" for Python code, but it
wasn't doing this config for the non-2D versions.  I've checked in code
to always do the pack alignment setting in the "traditional" (non-raw)
API.  If you want to test with that, pull from bzr.

HTH,
Mike
