@Jeroen Have you got any idea what's causing this error to be logged, or is it not serious enough to worry about? :

I *think* this is because it is trying to open images from the skins /media dir. And I don't think this is allowed or do-able.
Try to use default images with special:// pathnames.
I did replicate this on Grid once since this post, and can't repeat it. I think it is when coming from horizontal to vertical menu. It may be the default bg var, I saw one that has a default media/dir/etc path.
Maybe change all default images to special://skin/extras/etc.png or w/e.

I would ideally need debug logging enabled for it to catch the error outputs if it occurs again.
Meanwhile I'll try to make the color op more robust.

Right, so from the top of my head the only thing applicable would be the default fallback image, however this is / should only be shown when no background is set at all on the homescreen.

Regardless, one of my todo's involves making that background images customizable anyway, so moving it out of the media dir would serve both.

Thanks for the assist @badaas
