dconf-editor always prints warnings: "Unknown property on <schema>"

[Charles Kerr]

When I start dconf-editor, these four warnings are logged:

> ** (dconf-editor:30049): WARNING **: dconf-schema.vala:330: Unknown property on <schema>, extends
>
> ** (dconf-editor:30049): WARNING **: dconf-schema.vala:330: Unknown property on <schema>, extends
>
> ** (dconf-editor:30049): WARNING **: dconf-schema.vala:401: Unknown tag <comment>
>
> ** (dconf-editor:30049): WARNING **: dconf-schema.vala:401: Unknown tag <comment>

It doesn't seem to affect operations so I'm setting the initial importance to "Low".

This is reproducible for me every time I start dconf-editor from the command line.
