Bug#1101135: gnome-settings-daemon: Unwanted "Add Keyboard Shortcuts" window every time upon opening Ungoogled Chromium

[Fainche]

Package: gnome-settings-daemon
Version: 48.0-1
Severity: normal
X-Debbugs-Cc: old-attic-breeches at duck.com

Dear Maintainer,

I am using the Ungoogled Chromium flatpak, and every time I open it I get a popup nagging me to add keyboard shortcuts.
Temporarily dismissing the popup causes it to appear again every time a browser window is opened.
Firefox isn't effected by this problem.
This started happening immediately after apt upgrade yesterday, so it is definitely a problem introduced by the upgrade to 48.

Expected behaviour is that this window does not appear unless manually invoked.
