License-Question (expanded GPL)

[Cord Beermann <cord@debian.org>]

Hi.

I want to add a package to Debian with the following
License-Statement:

------------------------------------------------------------
The Simple PHP Blog is released under the GNU Public License.

You are free to use and modify the Simple PHP Blog. All changes 
must be uploaded to SourceForge.net under Simple PHP Blog.

Credit must be give to the original author and the Simple PHP Blog
logo graphic must appear on the site and link to the project
on SourceForge.net
------------------------------------------------------------

Does this make the package incompatible to DFSG?

Cord
