No attribute 'UNUSED_NONZERO_LOCATION_ERR' when projecting

I've just upgraded PyOP2, Firedrake, FFC and UFL. I now get the following error when running the swe_dam_break_1d test case (in the firedrake-fluids repository):

Please update and reinstall petsc4py, should fix things.

[ctjacobs]

That has indeed fixed things. Thanks.
