Ubuntu doesn't use su-to-root, should use gksu

Binary package hint: luckybackup

Upstream dev sent the following to the MOTU list:

I am the developer of luckybackup
(http://luckybackup.sourceforge.net/index.html) which you have included in the
universe repo (http://packages.ubuntu.com/karmic/luckybackup) and I thank you
for that :)

The application uses 2 .desktop files.
One of them is for super-user execution.
Since your package is a "copy" (I do not mean it in a bad way, please do not
missunderstand this) from the Debian repo, there seems to be a problem with
it.

Could you please do your magic tricks and patch the file:
menu/luckybackup-gnome-su.desktop
so that the following line:
Exec=su-to-root -X -c /usr/bin/luckybackup
becomes
Exec=gksu /usr/bin/luckybackup
