This is now fixed both upstream in libexiv2 0.27.5 with https://github.com/Exiv2/exiv2/pull/1918/commits/8a1e949bff482f74599f60b8ab518442036b1834 and in Gwenview for version 21.12.1 with https://invent.kde.org/graphics/gwenview/-/commit/91fcbe9c63c17bc20dbb3dd90e0451997f1c78a6 by Lukáš Karas.
The fix in Gwenview has not been merged into master and will not be present for example in future Gwenview 22.04 because we expect packagers to have shipped the fixed libexiv2 versions by the time Gwenview 22.04 is released.
