Matt, my prior error below is not related to the previous problem. But it does bring up a weird issue I thought you'd be interested in. I did not define any refinement criteria, but Enzo is writing the parameter "RefineBy" as =4 by default in a unigrid run. This is causing yt to use something called "overlap_proj"? Which is crashing the projection. If I go back and set RefineBy=2, the problem vanishes. This is maybe more of a Enzo issue than yt, but if one is using non-factor-of-two refinement, it could cause problems. Could this be related to Dave Collins' problem with RefineBy=4?

Okay, let's back out that changeset. I think it is okay to mandate an instantiated hierarchy if you want to have detailed, output-specific field information.

Not sure why that occurs. But I think Matt is definitely right about h5py:

Hi Stephen,
A bunch of people have been reporting segfaults. I am starting to think it may be an issue of an older h5py combined with this change, which may build up multiple copies of the hierarchy and keep multiple copies of a file (in this case the data file) open.
I think we should consider backing this change out, and providing it in a more subtle way -- for instance, making field info just always create the hierarchy. Here it actually almost always creates it twice. Remove the deletion, just leave the hierarchy in existence.

Bah humbug.
I did a fresh install on my mac, and the problem went away. I wonder what cruft I had left over was getting in the way? I deleted the .yt file etc...
Anyway, sorry for the noise, move along.
