PAR/REC failure to load ('BinOpener' object is not iterable)

I understand the PAR/REC is not super-well supported, but I'm now getting a strange error. Running from HEAD:

>>> from nibabel import parrec
>>> test = parrec.load(par_fname)

TypeError: 'BinOpener' object is not iterable

I don't have a ton of free time at the moment, so hopefully this error makes the problem immediately obvious to someone on here. If not, I'll figure it out and submit a pull request.

Could you give this branch a try? https://github.com/matthew-brett/nibabel/tree/fixing-parrec

It's in a current pull request : https://github.com/nipy/nibabel/pull/227

Works perfectly. Thanks!
