I believe the test outputs are flakiness and no true errors (you can run individual tests by giving their name to test.py): ./test.py PythonCode_MultiAppendShiftMethods . Could you verify this?
Otherwise I cannot reproduce this bug. I guess there is some plugin or Vim setting intertwined with Ultisnips which trigger this error. Can you try reducing your config to a minimal reproducable case?
