I'm observing some strange behaviour when using the inverse of a scalar. 
Running FFC on

  P1   = FiniteElement("Lagrange", "triangle", 1)
  v    = TestFunction(P1)
  temp = Constant("triangle")
  Tp   = 10
  L    = v*temp*(1*Tp)*dx

is fine, but running

  P1   = FiniteElement("Lagrange", "triangle", 1)
  v    = TestFunction(P1)
  temp = Constant("triangle")
  Tp   = 10
  L    = v*temp*(1/Tp)*dx

leads to the below error. For complex forms, I don't get an error when 
using 1/a, but the forms expect the wrong number of arguments.
