In the source code, the license header have been copied from somewhere without being completed, resulting in:

<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 2011 <copyright holder> <email>

The first line should be replaced by an actual description while the second line should be replaced by a list of copyrights with the contributors.

I'm not sure the GPL license is valid if these are left empty.

Ehheheh, I think licensing is the least of our problems, but If you want to write up a proper header I will make the changes and commit them once I get some free time.

Edit: Is this header suposeto be added to every .cpp and .h file?

Yes, it's usually added to each source file, as explained here : http://www.gnu.org/licenses/gpl-howto.html
