I have not pushed recent release to Fedora 25. Can you verify if this scratch
build works for you?

Do you have any external font installed? I mean font that is not installed by
any official Fedora package. I looked into the strace but I could not get
anything from it to understand this segfault.

On my F25 VM, I can use fontforge without any issue.

I try it on clean Fedora 25 VM, and it works fine - sorry for bothering you, I
have probably issue in my main machine. Closing as NOTABUG.
