Bug#792078: cantor-backend-qalculate: GPL3 not documented/incompatible mixing of GPL2/3 code

[Scott Kitterman <debian@kitterman.com>]

Package: cantor-backend-qalculate
Version: 4:4.8.4-2
Severity: serious
Tags: upstream
Justification: Policy 2.3

  I am going to accept this package, despite some issues with licensing.  The
  major issue is the combination of GPL 2+ and GPL 3+ code in src/backends/
  qalculate/ that does not appear to be mere aggregation plus the lack of a
  copying file for GPL 3.  Either the two GPL v3 files should be relicensed by
  the copyright holders as GPL v2+ or a COPYING.GPL3 should be added (in which
  case the combination is allowed by upgrading thing to be effectively GPL3.
  
  I checked, and this problem goes back to wheezy, so since it's not new, I
  won't reject for it, but will file a bug instead.  Please work with upstream
  to get this resolved.
