rB67e23b4b2967 revealed the bug. But the bug already existed before, it just wasn't triggered. Apparently the problem happens because the python code generated in `initGuiding()` cannot be executed twice. The second time the `initGuiding()` code is executed, the local python variables are removed to make way for the others, but the reference to one of the grids in a `Solver` object (name='solver_guiding2') is still being used somewhere. So an error is raised and a crash is forced. The solution is to prevent the python code in `initGuiding()` from being executed twice. When `FLUID_DOMAIN_ACTIVE_GUIDE` is in `fds->active_fields` this indicates that the pointer in `mPhiGuideIn` has been set and the guiding is already computed (does not need to be computed again).
