[Pkg-fonts-devel] Bug#656359: [Pkg-fonts-bugs] Bug#656359: Bug#656359: Segfault when pressing modifier/arrow keys if more than 4 points are selected

[Khaled Hosny]

I use FontForge extensively I never encountered this, and generally it
is less crashy than it used to be. May be it is 64bit specific bug?

Regards,
 Khaled
