Thanks Łukasz
With regards to the gnome-desktop3 patch. I had a look through the
gsettings API and there didnt seem to be a method to say "is this
gsettings key you are about to use valid" - in fact all the
documentation basically says it is up to the programmer to ensure that
a key being used is actually there ("programmer error"). GSettings
doesnt seem to-do any validation which is a shame.
I would prefer if the whole "draw-background" ubuntu patch could be
dropped (and hence make this patch unnecessary) but I don't know
really what the current impact that would have on the Unity desktop.
Ack with regards to the static functions in gnome-screensaver. I
suppose its a coding style to keep code as localised as possible.
I did ping on both #ubuntu-devel and #ubuntu-desktop recently but no
takers. I don't really know anyone on the GNOME team other than
JBicha.
