Hi,
This is a system configuration and/or GLib bug, depending on how you
look at it.
If you examine each $PREFIX/glib-2.0/schemas for each $PREFIX in
$XDG_DATA_DIRS, you will find one of the prefixes before /usr/share
contains an old schema XML file for Geary that does not contain the
missing key. This is being found before the packaged schema in
/usr/share, and hence GSettings cannot find the updated schema.
To fix, remove the old schema file, then recompile the schemas there
using `glib-compile-schemas PATH/TO/SCHEMA_DIR`.
I recommend closing this bug or moving it to GLib, in case they are
interested in fixing the root problem.
