Comment 9 for bug 24280

I think when you launch an application with gksu, it be save the actual user session environment .

for example, when you execute "su user" you change the user but all session environment don't change and when you execute "su - user" then the session environment change to the user logged.

I think that if you launch some application with gksu it may use the user theme and "gksu -" the root theme.
