Following README example leads to a crash

Hi Max,

I was hoping to try out classy for taking a closer look at the specific asteroid - it used to work fine but it's been a while! Now, following the examples given in the README file leads to a crash:

$ classy classify --wave_min 0.45 --wave_max 1.8 --family Themis --albedo ,0.06
Traceback (most recent call last):

ValueError: cannot insert filename, already exists

Same thing happens on both my Arch Linux and Ubuntu systems. A simpler command like classy classify 2017BW works, so the setup can't be entirely broken :)
