In attempting to make a series of projections with halos plotted using the public install of yt on Kraken, I've encountered an odd problem.  The job terminates without giving an apparent error statement in the output files, but rather ends with this cryptic (at least to me) mess:

h5py._stub.IOError  File "h5g.pyx", line 104, in h5py.h5g.GroupIter.__init__ (h5py/h5g.c:1248)

Does anyone have an idea what could be causing this problem?

Thanks,
