[Pkg-fonts-devel] Bug#976293: fontmatrix: segfault on selecting shaping

[Adam Borowski]

Package: fontmatrix
Version: 0.9.99-2
Severity: normal

Hi!
When viewing a font that includes shaping variants (fonts-elstob in this
case), if you select something from the "shaping" menu (it's grayed
otherwise), I get the following splat:

hread 1 "fontmatrix" received signal SIGSEGV, Segmentation fault.
