Comment # 8 on bug 970653 from Donald Curtis

"Look And Feel": Oxygen
"Desktop Theme": Oxygen
"Mouse Cursor Theme": Oxygen
"Splash Screen Theme": Oxygen
"Application Colour Scheme": Oxygen
"Icon Theme": Oxygen
"Widget Style and Behaviour": Oxygen
"Look and Feel of Window Titles": Oxygen

In the "Add Widgets" Panel, the "Lock/Logout" Widget shows the Oxygen icon.
In the Panel, the "Lock/Logout" Widget has the Breeze icons.
In the "Add Widgets" Panel, the "Application Menu" Widget shows Oxygen icons.
In the "Application Menu" most of the Favorites (Firefox, Konsole, Dolphin) are
using Oxygen icons except, for the "Leave" icons (Logout, Shutdown, Reboot):
Breeze . . .
The "System Tray" Icons are also still Breeze style.

[Naming is taken from an en_GB User]

A de_DE "Oxygen" User on the same system also exhibits the same "Breeze" icon
issue.
