Changeset:   3200f58ed8e7
Branch:      yt
User:        ngoldbaum
Date:        2013-05-21 03:05:44
Summary:     Adding a catch for plots of all-zero arrays.  Closes #572

Currently these sorts of plots will crash if the colorbar is logarithmic.  This
forces a switch to a linear colorbar to avoid the crash.
