[yt-users] particle read error

[david collins]

Hi, all--

I have a set of clumps that I've pickled to disk, now I've unpickled
them and I'm trying to get some particle info.  When I try to access
the particle indices from the clump (in the error message, it's c1) it
throws the following error.  I do the same thing again, and it works
fine (that is, access particle_index on the same c1, returns a
reasonable looking particle list)  I'm probably doing something dumb,
do any of y'all see what it is?

Thanks,
d.
