[Tango-artists] CC-SA & GPL Compatibility

[Michael Schurter]

Hello all,

I want to distribute some Tango icons with my GPL'd PHP project, 
OpenIT[1], but as far as I can tell the Creative Commons Share-Alike 
license is incompatible with the GPL.

The FSF thinks its incompatible[2], and the Debian project does not 
consider a free license.[3]

However, since Tango icons are intended for use on GPL licensed software 
such as Gnome & KDE, I suspect I'm not understanding something.

To summarize:
Can Tango icons be distributed with a GPL project?
If not what is there another suggested license to use for my project?

Thanks for the great icon library,
Michael Schurter
