gimp crashes when it tries to find newly installed font

[soursop]

I'd like to get an emoji font for my Gimp 2.8 on Linux Mint 19.1. So I downloaded https://github.com/MorbZ/OpenSansEmoji and copied to /usr/share/fonts/truetype/ . when I try to find the font in the dropdown list, gimp gives this error:

Quote:~ $ gimp

1. Segmentation fault

How can I fix?
