Including Poppler code in CUPS is no problem with the license. Poppler 
is GPL. Probably the problem is that he wants to have copyright on the 
full source to be able to also include it in closed-source software and 
he probably also does not want to duplicate the Poppler source code 
(therefore he also changed the pdftops filter to call the pdftops tool 
from Poppler or xpdf instead),

As your current PDF filters go deeply into the Poppler source code I 
think the best place for them is the Poppler project.

Can you talk with Mike about including only the imagetopdf filter, as it 
does not use Poppler and goes deeply into the CUPS code. Tell Mike that 
you would transfer copyright to him and agree with him that the filter 
gets into CUPS under the same license as CUPS itself.
