WP Mobile Edition missing background.png in /img

Hello,

at first I`m sorry, because I postet this issue as comment in your blog.

What my question is:
I use this wunderfull plugin in several blogs of mine. But an error occurrs, if s.o. comes with a mobile device to my site. On line 21 of your \wordpress-mobile-edition\carrington-mobile-1.0.1\css\advanced.css stands: background:#e5e5e5 url(../img/background.png);
But there is no background.png in directory /img.
Can you please fix that problem?

Thx in advanced
