• Right now we bundle an old version of Scour that is dual-licensed with Apache 2.0 license and GPLv2+. This dual licensing was only introduced in a very recent commit [1] when the original author Jeff Schiller agreed to re-license his code under the terms of GPLv2+ after license issues in Inkscape were brought up in a previous discussion [2].
  However at this point there were multiple contributions to the Scour codebase by other authors who did not accept to re-license their contributions. This is why the re-licensing is likely to be void and the the current maintainer of Scour (Tobias Oberstein) decided not to apply the dual-licensing when switching over to GitHub with the project [3].
  
• I recently updated the Scour extension for Inkscape and want to merge these changes [4]. Obviously I followed Tobias Obersteins decision not to apply the dual-licensing, so the new version only has the Apache 2.0 License.
  
• The open question now is: Can we bundle the Scour code with Inkscape and how to we do it?
  

In my opinion this should not be a problem since Scour is an external module that is *indepentent* from Inkscape, e.g. license incompatibilities do not play a role here which is also the opinion of Tobias Oberstein (see [5] for details and references). Also most project members seem to agree (see comments in the merge request [4])

However If we don't want to follow this reasoning we have to decide on alternatives (especially since the code currently in trunk might well have an invalid license).

I hope we can once and for all resolve this issue!

Eduard
