[yt-users] h5py error in plot call

[Jordan Thomas Mirocha]

Hello,
The other day I updated to h5py 1.2, and am now getting the following  
error message when I try to make projections or slices.

yt         INFO       2010-02-14 16:25:07,976 Created plot collection  
with default plot-center = [0.5, 0.5, 0.5]

Any ideas?
