examples/all_the_things.py broken

examples/all_the_things.py appears to be returning FAIL due to this test phase:

@htf.measures(
htf.Measurement('replaced_min_only').in_range('{min}', 5, type=int),
htf.Measurement('replaced_max_only').in_range(0, '{max}', type=int),
htf.Measurement('replaced_min_max').in_range('{min}', '{max}', type=int),
)
def measures_with_args(test, min, max):
test.measurements.replaced_min_only = 1
test.measurements.replaced_max_only = 1
test.measurements.replaced_min_max = 1

The logging output to stdout/stderr indicates a FAIL, but no indication of what failed. Not sure if expected behavior is to also include reason for failure.
