Hi Michael,

Thanks for filing this bug report and providing the proposed solution.
I myself also have some troubles with certain themes but those are themes not provided by Ubuntu.
In your proposal you uncomment this line:

 # Glow the tasklist by changing the color, instead of overlaying it with a rectangle
 WnckTasklist ::fade-overlay-rect = 0

From some doc at http://live.gnome.org/GnomeArt/Tutorials/GtkThemes/StyleProperties the fade-overlay-rect property is described as:

Name: fade-overlay-rect
Type: boolean
Default: TRUE
Nick: Overlay a rectangle, instead of modifying the background.
Description: Compatibility mode for pixbuf engine themes that cannot react to color changes. If enabled, a rectangle with the correct color will be drawn on top of the button. Default: TRUE

which makes me believe this solution may work in certain situations (pixbuf engine) though not always. In other words the authors of the theme will have had a reason to comment the line out.
