Public bug reported: This issue is only about the loupe snap. We don't have a problem with loupe or glycin as .deb's.
We are blocked from updating the Loupe snap past version 46. Loupe is GNOME's new image viewer app and it relies on glycin for loading images (basically a next generation gdk-pixbuf). glycin uses bubblewrap for sandboxing. Loupe 46 uses glycin 1.0, Loupe 47 uses glycin 1.1 and Loupe 48 uses glycin 1.2. Beginning with glycin 1.1, the glycin developers removed the option to disable the bubblewrap sandbox. Therefore, as a first step, it would be nice to be able to build loupe 46 without setting -Ddisable-glycin-sandbox=true When I tried running loupe built like this, the app opened but I was unable to open a .jpg. Screenshot of the error message attached.
