Bug#852290: inkscape: saving as "optimised SVG" fails, due to error when importing scourString

[Tim Wienk]

Package: inkscape
Version: 0.92.0-3~bpo8+1
Severity: normal

Dear Maintainer,

Please note, this bug only applies to Debian Jessie (using inkscape from
jessie-backports and python-scour from jessie - there is no backported
version of python-scour).

When saving as an optimised SVG, inkscape uses the scour library to
optimise the SVG. An error is reported when doing so, triggered by
importing `scourString` from `scour.scour`.

The problem is most likely a result of a change in the python-scour
package:

- In package version 0.26-3 (jessie), scour.py exists as:
  /usr/lib/python2.7/dist-packages/scour.py
- In package version 0.32-2 (stretch), scour.py exists as:
  /usr/lib/python2.7/dist-packages/scour/scour.py


I have implemented the following patch locally to work around the
problem:

Thanks for the continued work and effort on maintaining this package.

Kind regards,

Tim.
