I downloaded the icons from that page, and the picture embedded in
thumbnail.py is not there. However, there is one *very* similar.

See attached. Since this appears to be a derivative work, but with
a different license ("freeware"), I'm not sure if we can include it.
Are we in a position to enforce the GPL like that?

Maybe we could track down the commit that added it and ask the author?

I've applied the other patches, thanks a lot for this
unbundling work!
