The demo pde/simple/python is failing with the following message on
the buildbot:

  ----------------------------------------------------------------------
  ./../../demo/pde/simple/python (Python)

  RuntimeError: *** Error: Form expects 1 FunctionSpace(s), 2 provided.

I saw this once yesterday on my laptop but then it mysteriously went
away after I corrected a typo in the error message in Form.cpp...

Is anyone else seeing this problem and able to debug it? I can't seem
to reproduce it here, with or without instant-clean.
