Bug#879229: gnome-characters doesn't start

[Nicolas LE CAM]

Package: gnome-characters
Version: 3.26.1-2
Severity: important

Dear Maintainer,

Upgrading gnome-characters to 3.26.1-2 renders the app unusable.
Going back to 3.24.0-1 fixes the problem.

When launching the app the following error is outputed :

(org.gnome.Characters:25998): Gjs-CRITICAL **: JS ERROR: SyntaxError: missing : after property id @ resource:///org/gnome/Characters/js/characterList.js:551
JS_EvaluateScript() failed

regards,
Nicolas
