It's not that easy, I'm afraid. 

The application you want to run with "gksu" can be in the need of calling 
additional libraries that are not located inside the "~/.config" 
directory but system wide.

So why don't you just run...

gksu -d chromium
gksu -d qbittorrent

And tell us what happens? :-)

Try and tell.

I meant directeories under "~/.config".

Okay, run "ls -la .config/*/" so we can see what's in there...

Then find where are those applications storing the configuration data, it 
has to be somewhere under the user's profile.

What a mess!

It should be just fine with "gksu -l newuser qbittorrent"

("man gksu" for additional parameters to keep/discard the current user 
environmental variables)
