This is not a bug, but a feature request.
I think that it would be very nice if wicd would use the same icons NetworkManager uses now.
1: Now wicd uses only 22x22 icons. But not each panel has the icons of this size. For example, I use a bmpanel2 theme, that uses 16x16 icons, and resizing of 22x22 to 16x16 just does not look good. Using GTK+ icons will make it much easier to adapt to different panel sizes.
2: All of the icons wicd has are covered by GTK+ icon styles. Except for 'lock' versions, but in the wicd icon set these icons do not differ from the usual ones. Also, I have never seen ones, and if the user just can not change the network settings, it doesn't have to be indicated with a tray icon. For example, the reason of Ubuntu bug #1 doesn't do that. And the icons in wicd, IMHO, are *worse* than GNOME or GNOME-Colors ones.
