You shouldn't get any frequencies because your k point is zero, and you are putting in an exp(ikx) source that fills all space. The corresponding eigenfrequency is zero, but harminv can only find non-zero frequencies.
(I'm surprised you find some frequencies when you use an Ez source, because tried your file and I don't get anything in this case either. Maybe harminv is picking up some tiny numerical noise.)
I just tried a quick calculation (changing the cell to 2d) where I set the k point to be nonzero (0.5,0.3,0), and both the Ez and Hz source correctly return a frequency of about 0.583.
