Bug 357202

Menus in the Desktop Wallpaper Settings Plugin obey the color scheme when presenting text but don't obey the color scheme for the background of that text. They use a white background while also using the white text as defined. The result is white text on a white background which is completely unreadable. It's only possible to see what the menu entries are as they are highlighted during mouseover.

Reproducible: Always

Steps to Reproduce:
1. Choose a dark theme
2. Right-click on desktop and choose Desktop Settings
3. Click the Wallpaper Type drop-down menu

Actual Results:  
The drop-down menu displays an empty white rectangle with a single highlighted entry showing the currently selected wallpaper type. The reason the rest of the rectangle is empty is that the text is the same color as the background: white.

Expected Results:  
The drop-down menu should display a list showing what wallpaper types are available. This list should be displayed as white text on a black background.

Appearance Settings In Use When The Linked Screenshot Was Taken

-Workspace Theme-
Look And Feel: Breeze Dark
Desktop Theme: SimpleGrey

-Color-
Scheme: vertex negro

-Application Style-
Widget style: Breeze

There is not a "Breeze Dark" widget style. This should not matter for the drop-down menu because drop-down menus in other settings windows do not have this problem.
