Ah, thanks for the tip.  Guess I should have looked at the code!  I managed to get past that error by making the following modification: http://paste.yt-project.org/show/4859/

Sadly it dies a little further on with this error: http://paste.yt-project.org/show/4860/

When I poke around with a debugger, it looks like it's trying to access field data for the level-2 clump region, but the data object is empty.

Sorry, let me rephrase that: I completely rewrote the *contour
identifier* for 3.0.  The clump finder is a layer on top of that.
