Bug#334050: Tray Icon's Background is White instead of Transparent

[Martin Samuelsson]

Package: gnome-cups-manager
Version: 0.31-1
Severity: minor

While fruitlessly trying to solve #295492, I realized this package has
the same problem.

gnome-cups-icon's tray notification icon has a white background instead
of a transparent one. This results in a weird look on a non-white panel
background. No biggie, but it'd be nice if it could be fixed.

I tried fixing it, but my gtk/gdk skills arn't that good. The following
message could be a hint, but it didn't get me all the way.
