So, I have rebuilt a GTK3 snap using snapcraft version 2.34 on Ubuntu Server 16.04.3 LTS.
I get this error message when I run the snap:
**(app:3456): GLib-GIO-ERROR : No GSettings schemas are installed on the system
Since my source and snapcraft.yaml has not changed, I am going to assume that the issue is not therein.
I compared the “desktop-launch” script from a previous (working) snap with the newly built snap. They are slightly different because of some very recent change to snapcraft I assume.
Perhaps there is some bug in there? Specifically at function compile_schemas()? Maybe this is due to some recent change by: @jamesh in this thread?
