CSS problem in Administration pages : unaesthetic 15px empty space under slogan

Tested in Firefox 3.5, Chrome 4.0 and Safari 4.0, there is a unaesthetic 15 px empty space between logo container and slogan header in administration pages only.

This is due to /modules/system/admin.css 1.18.2.1 Line 20 to 22 :

div.admin {
  padding-top: 15px;
}

Attached is the proper patch to be applied to « simply_moderne/style.css » :

div.admin {
  padding-top: 0px;
}
