FilterProxy and DFSG-compliancy?

[Kenneth Vestergaard Schmidt <charon@debian.org>]

Hi!

I just filed an ITP in response to an RFP for the package "FilterProxy". 
However, I might have jumped ahead too quick, since the license might be too 
restrictive.

It /does/ fall under the GPL, but with modifications. This imposes two 
problems, one minor and a lesser one.

The first is, that one lines is added at the top of "COPYING". That one
line can just be added verbatim to "debian/copyright", and then provide the 
usual reference to /usr/share/common-licenses.

However, what the line states is:
"Please see the file LICENSE for a modification to the license for 
FilterProxy"

I have attached LICENSE to this post - hope nobody minds, it's only 3.6kb. I 
really need some input on this - would it be against the DFSG? I wouldn't 
think so, only the long description should contain the license, and 
README.Debian should probably contain a notice. But should it go in non-free? 
Or is it totally against the DFSG?

Anyway, any input is appreciated.
