Copyright on owncloud background

Server

hi guys,

I was wondering if the owncloud 10.0 background had/has any copyrights on it?
I'm talking about this picture:

background.jpg1920x1280 130 KB

am I free to use it or do I have to find myself another picture?

I would imagine that it is covered by this or this (the files distributed with the ownCloud software).
