Failed to parse translated string on dconf-editor launch

[lotuspsychje]

Ubuntu 18.04.2 LTS with kernel 4.18.0-25-generic up to date @ 22/7/2019

On the launch of dconf-editor from terminal, it produces alot of errors on gnome-boxes like these:

lotuspsychje@Rootbox:~$ dconf-editor

(dconf-editor:22844): GLib-GIO-WARNING **: 20:00:22.468: Failed to parse translated string '[‘Werk’, ‘Onderzoek’, ‘Spelletjes’]' for key 'collections' in schema 'org.gnome.boxes': 1:expected value

(dconf-editor:22844): GLib-GIO-WARNING **: 20:00:22.469: Using untranslated default instead.

The errors can be reproduced with clicking every value under /org/gnome/boxes

tested dconf-editor export LANGUAGE=C

and no errors there, so probably its the dutch (or other languages) translation that lacks

I tested exporting locales on french and german
and native english, all 3 did not give errors
