It's actually a bug in the viewer.py script (systembuttonface isn't
defined in Unix versions of Tk(inter)):

Here's an improved version, which uses a temporary label widget to get
the correct background colour:

    # handle transparent images

    w = Label()
    r, g, b = root.winfo_rgb(w["background"])
    rgb = r / 256, g / 256, b / 256

(from 0.2b5, which I hopefully will get time to release real soon now...)
