This morning I was prompted to upgrade some packages including ffc etc. I said 'yes'. But after the upgrade, I found form compiling broken.

For example, when I compile the Mixed Poission demo, I got the following error.

chong@chong-desktop:~/build/demo/pde/mixed-poisson/cpp$ ffc -l dolfin MixedPoisson.ufl 
This is FFC, the FEniCS Form Compiler, version 0.9.0.
For further information, visit http://www.fenics.org/ffc/.

An exception occured during evaluation of form file.
To help you find the location of the error, a temporary script
'MixedPoisson_debug.py'
has been created and will now be executed with debug output enabled:
Traceback (most recent call last):
  File "/usr/bin/ffc", line 167, in <module>
    sys.exit(main(sys.argv[1:]))
  File "/usr/bin/ffc", line 138, in main
    ufd = load_ufl_file(filename)
  File "/usr/lib/python2.6/dist-packages/ufl/algorithms/formfiles.py", line 92, in load_ufl_file

  File "/home/chong/build/demo/pde/mixed-poisson/cpp/MixedPoisson_debug.py", line 23, in <module>
