Hi everyone,

I'm having a problem using fields that use ghost zones.  The following simple script:
http://paste.yt-project.org/show/2010/

gives this error:
http://paste.yt-project.org/show/bOikDPScBBtDiUGvH11X/

I am working from the tip, but I get the same behavior from yt/2.3.  In yt/2.2, everything is working.  I am working now to narrow that range down a bit, but does anyone have an idea?
