fontforge compilation failed - segfault

[Averethel]

I installed the newest version of fontforge (via homebrew) and since then it does not work.

Debug output:

       debug  Using settings from `fontcustom.yml`.

After that, I tried to manually execute fontforge with the same arguments as the gem does it. The result is:

fontforge --script ~/.gem/ruby/2.3.3/gems/fontcustom-2.0.0/lib/fontcustom/scripts/generate.py .fontcustom-manifest.json

I checked if this could be related to broken python libraries but it seems that they can be loaded.

python -c "import fontforge"

works as expected
