Problems with test public.min_path.energy_small2

when i execute all tests ./run_tests.py i got this fail message
unknown
to my knowledge the picture small2 only has 3 x 3 pixels so how could there even be a fifth pixel in the last row?
as i recall it also said "energy at 0 : " at some point and i dont understand why the test parameters are changing
i also get similar problems for test public.min_path.min_energy_wide_1
(edit: min_path.min_energy_wide_1 this test i actually pass but i have the same issues with min_path.energy_wide)

yeah that helped me solve it , thanks
