In previous versions of DOLFIN, a user was able to define a function

FunctionSpace gets attached to the user function and then I get a
runtime error when it is used in another form. Is there a way to tell
the function to delete the current function space?
Any help is appreciated.
Which version are you using? 0.9.3 or hg tip?
I'm using 0.9.3. I'm way to slow to keep up with the tip =D.
We've been redesigning the function classes since 0.9.3 to make these
things work better. In particular, a user must now subclass a new
class named Expression which never has a FunctionSpace attached to it
so you should be able to use it in many forms, as long as the shape
(rank and dimension) of the expression matches.
Okay, I'd like to release my library against 0.9.3 so users can have a
stable release but I will watch out for these changes.
