Bug#860991: Bug#859093: colord-kde is missing in stretch

Control: retitle -1 "gnome-color-manager: double-free in the argllcms fallback code"

¡Hola Christian!

I'm forwarding the gcm-calibrate part of your report to the 
gnome-color-manager maintainers, it seems that the issue is solved upstream 
with the patch: 
https://github.com/GNOME/gnome-color-manager/commit/edd8cf7598c009c8494396663401da80d12caf9d

Still, I don't have the hardware to test this, maybe the gnome-color-manager 
maintainers can test this, otherwise, they may need you to test the patch.

I've set the severity to important, but it could equally be considered grave.
