[yt-users] pc.save with old Enzo

[Elizabeth Tasker]

Sorry -- correction: this problem also occurs with a new data set from Enzo 2.0. It doesn't happen, however, with the older version of yt. 

The version it fails on is 9cb628620da6 (yt). Unfortunately, the version it works on gives an error linked with finding the mercurial libraries when I run yt instinfo, so I'm not sure which version it is.
