Download Builder Won't Download Custom Themes

[kingjeffrey]

Download Builder appears to be broken again. It will not download custom themes. All the parameters are being passed to the download url, but the custom theme provided in the download is "smoothness".

The theme I am trying to generate:

That URL didn't work for me, but building a custom theme did. Please try building your theme again.

I've verified the problem is with specifying a two-word font name (such as "Helvetica Neue". This breaks the theme, and is reproducible.

The problem you're describing is #4379.
