KeyError: 'max_local_dimension' in formatting.py

Hi,

i just installed FEniCS using Dorsal (stable=true, snapshot=false) on my Ubuntu 12.04 system. However, I ran into some (probably) FFC-related problems which I don't understand.

Since I first thought it might be some problem with my own code, I ran an example and got the following:

$ python demo_cahn-hilliard.py
Calling FFC just-in-time (JIT) compiler, this may take some time.
Traceback (most recent call last):

KeyError: 'max_local_dimension'

I searched for max_local_dimension, but found no answers. Is this a known problem? If yes, does anyone have an idea on how to fix this?

Best, Christian
