I assume you do not have a clean install of 0.6dev, but there are still
some leftovers of previous versions lying around. The traceback you
provided has this:

The file mvpa/datasets/nifti.py was removed almost exactly a year ago
with this commit:


I guess the best strategy would be to completely remove PyMVPA from your
system and reinstall a fresh and clean 0.6.dev snapshot. How did you
install it previously?

If you experience problems please report them and we'll sort them out.
