Details

Description:

The current version of the gnome-font-viewer cannot be used. It will crash with a segfault.
The stacktrace suggests that the gnome-font-viewer.mo file is not available.

When successfully running locale-gen again, it will not create any gnome-font-viewer.mo; not in en_US, not in en and not in other language-specific folders.


Additional info:
* package gnome-font-viewer
* build date Sun 09 Apr 2017 12:29:46 AM CEST
* currently in testing (3.23.91+2+g419afa1-1)

Steps to reproduce:

Open a TTF file with gnome-font-viewer. It will crash.
Try not to open a TTF file with gnome-font-viewer (to view all installed fonts). It will crash.
Reason is probably the missing translations file.

I tried to reproduce and opening gnome-font-viewer won't crash it, but it will crash if I try to open a ttf file.
Opening a TTF file when gnome-font-viewer is already running works fine.
