Hi All, 

I'm seeing an error when I run YT 3.2 in parallel. Running in serial mode everything is fine. I have a bunch of fields I'm creating profiles for 'DarkMatter' is not one of them but that's where it fails. It looks like its picking up the DarkMatter radius rather than the gas radius?

 rp = yt.create_profile(sphere, 'radius', Fields,
                               units = {'radius': 'kpc'},
P002 yt : [ERROR    ] 2015-05-14 22:09:54,308 YTFieldNotFound: Could not find field '('DarkMatter', 'radius')' in RD0001.

I've attached the error file

and the version info is:

Version = 3.2-dev
Changeset = 3e1887de7362+ (yt) tip
