Dear Maintainer,
since the update of gnome-settings-daemon to version 46 in testing,
gsd-xsettings crashes while reporting
(gsd-xsettings:5037): GLib-GIO-ERROR **: 08:45:13.336: Settings schema 'org.gnome.desktop.a11y.interface' does not contain a key named 'show-status-shapes'
The backtrace doesn't say much more

The mention of "schema" led me to notice that gsettings-desktop-schemas has a newer version in unstable, and indeed upgrading that package (and the gir and dev packages that come with it) from 45.0-2 to 46~beta-3 seems to have fixed the issue.
My suggestion would be to tighten the dependency, which currently only says (>= 42~). Maybe in the very short term you could also ask if the migration of gsettings-desktop-schemas to testing can be sped up?
