Bug description:
bkehlet@bkehlet-laptop:~/software/dolfin/demo/ode/courtemanche/cpp$ ./demo 
Creating ODE of size 21.
Solving ODE over the time interval [0.0, 300]
  Initializing continuous Galerkin method cG(1).
  Using mono-adaptive Newton solver.
  Using discrete tolerance tol = 1e-08.
  Using uBLAS Krylov solver with no preconditioning.
  Using BiCGStab Krylov solver for matrix Jacobian.
  Time-stepping over the time interval [0, 300]
    Warning: consider implementing Jacobian ODE::J() to improve efficiency.
    *** Warning: Time slab system seems to be diverging.
    *** Warning: ODE solver did not converge at t = 0.25
  ODE solution computed in 0.010 seconds.
Total number of (macro) time steps: 0
Number of rejected time steps: 0
Function evaluations:  20
Potential at end time: 0.000000
