[Vala] GSettings and not-available schemas

Hi all:

I'm working with GSettings. I want to read org.gnome.desktop.background
and want to ensure that my code works even when the schema is not
installed (let's say, if the user is using KDE).

When I try to access an inexistent schema, I receive this message:

(cronopete:15673): GLib-GIO-ERROR **: Settings schema
'org.gnome54.desktop.background' is not installed

Trace/breakpoint trap (core dumped)

I tried to catch it with try/catch, but I'm unable: always got the core
dumped and the code ends.

I'm considering to read all the installed schemas and ensure that the
one I want is installed before creating the gsettings, but I'm sure
there must be a more elegant way of doing it. The question is: how?

Thanks!
