The license header in the artifact doesn't state the "or later", but
refers to the license as published by the FSF which does include it:

The full license text is not included in the header, but is deferred to
the license as published by the FSF. Since the licenses as published by
the FSF include "or (at your option) any later version" GPL-3+ applies.
QT projects include the LICENSE.GPL and LICENSE.LGPL files as referred
to in the header, but these are not included in qmapshack as they are in
QT projects. The LICENSE.GPL and LICENSE.LGPL files included in QT
projects are verbatim copies of the licenses as published by the FSF
which includes "or (at your option) any later version".
The QT code included in qmapshack is taken from the QT examples, and the
license applied to that include "or (at your option) any later version":

Leaving out the commercial licensing option is not ideal indeed. I
suggest to include the license header in the d/copyright as a comment
and keep the individual license specifications as they are now:
Files: src/helpers/CTextEditWidget.cpp
src/helpers/CTextEditWidget.h
Copyright: 2012, Digia Plc and/or its subsidiary(-ies)
License: GPL-3.0+ or LGPL-2.1 with Digia Qt LGPL Exception 1.1

License: QT
This file is part of the QtGui module of the Qt Toolkit.
...
Would conform to the copyright-format 1.0 specification.
If my suggestion above is not deemed appropriate, I suggest to to use
the license short name QT whose license specification is the text from
the header.

Exactly. I looked at how other packages had handled the QT specific
license in d/copyright. qt4-x11, which I looked at too, is not
appropriate as it doesn't use copyright-format 1.0.
qtmultimedia-opensource-src does use copyright-format 1.0 and includes
the text from the LGPL_EXCEPTION.txt text in the license specification
which was missing in d/copyright for qmapshack.
http://metadata.ftp-master.debian.org/changelogs/main/q/qtmultimedia-opensource-src/unstable_copyright
If we take the example of pulseview, we'd still miss the text from
LGPL_EXCEPTION.txt which is not included in qmapshack, but is included
in QT projects.
Kind Regards,
