Gimp cuts IPTC meta data
I use gthumb to add meta data (IPTC tags) to my pictures. For example: after adding the tags "quik" and "quak" and editing the picture with gimp (2.10.8, Debian buster), all tags but the first one are lost:
You can easily reproduce the misbehavior with the following commands:
gthumb test.jpg # categories -> quak, quik
exiftool -iptc:keywords test.jpg
Keywords: quak, quik # that's ok
gimp test.jpg # change something and save test.jpg
exiftool -iptc:keywords test.jpg
Keywords: quak # missing "quik"
