Non-DFSG compliant images in the Tails OpenPGP Applet
SVG Images included in the Tails OpenPGP Applet are licensed under CC-BY-SA 2.0. PNG licensing is unclear.
This license is not compatible with DFSG and this is usually considered
Serious bug by debian.
Theses images seem to be modified from the Tango Icon set, before it was
released to public domain.
According to intrigeri (see #6507 (closed)) :
I think these files were initially imported from seahorse-plugins 2.30.1-3 (commit df9d7209). I’ve checked its source, and it indeed lacks provision for the license these files are under.
- Convince upstream to relicense these images
- Modify these and use clause 4b of CC-BY-SA 2.0 to upgrade the license to a later version (3.0 is fine)
- redo these from a more recent Tango icon set (in the public domain)
Other packages from Debian seem affected : https://lists.debian.org/debian-devel/2014/08/msg00073.html.
