Severity: serious
Tags: upstream
Dear Maintainer,
After the upgrade from 6.9.10.14 to 6.9.10.23, I noticed that the
autopkgtests for the package ruby-mini-magick is failing due to one test
about checking units to show the size of the image in cm and inches.
I could isolate the problem by running the `identify` command on a test
image (rgb.png in the spec/fixtures directory of the ruby-mini-magick
source package).
Running:
identify -verbose -units PixelsPerInch rgb.png > output_in.txt
identify -verbose -units PixelsPerCentimeter rgb.png > output_cm.txt
diff -u output_in.txt output_cm.txt
gives me the following with 8:6.9.10-14 from testing:

Maybe it was induced by this change?
https://github.com/ImageMagick/ImageMagick6/commit/8c7648a1adf7bba35594074f191affd3ff3263bb
Attaching the reference image and the full output files.
I am setting severity serious, as it breaks the testsuite of
ruby-mini-magick and provides wrong data when identifying images.
Thank you in advance
Cédric
