[Bug 71937] gksu and kdesu ignore users font config

[sedd]

Public bug reported:

When an app is run in superuser mode, via gksu or kdesu, the users
~/.fonts.conf file is not used.  If ~/.fonts.conf is copy/linked to
/root/.fonts.conf for /etc/fonts/local.conf, then the sudoed app
respects the users font profile (as far as I can tell, this affects only
antialiasing, not choice of font face or size.)

To reproduce, open System - Preferences - Font menu and change the
antialiasing to something obviously different from the default. Run
gksudo gedit (or whatever) and notice the antialiasing. Does it use the
default aa settings?  Now run sudo gedit -- the custom antialiasing
profile is used, unlike with gksu. Why is this?

This affects both gksu and kdesu, so I don't think it is a bug with
either of them.

** Affects: kdebase (Ubuntu)
     Importance: Undecided
         Status: Unconfirmed
