Hmm, not sure to be honest. I suspect it's still related to gconf in
some capacity, but not 100% sure.

We'd probably need debug output from the server to debug further.

I know we have a gconf helper binary, but not sure when/how it's
launched if I'm honest, but I suspect that poking about in the
module-gconf code will maybe be the right direction.
