Johan,

This is the problem that I ran up against with FIAT 0.2.3 when using a
zeroth-order discontinuous scalar basis. When using the CVS version of FIAT and
ffc 0.1.9, I didn't have any problems (I tested it this morning). You must have
a problem with FIAT versions. My FIAT is /usr/lib/python2.*/site-packages/FIAT,
where "*" is the Python version. I think that this is the default location for
Python.
