Arch Linux

Description:

The colord package has a dependency on sane package which is listed as optional, but there's constant error logging if the .so is missing:
# journalctl -x --all --follow
Jul 08 08:24:03 zero-unity colord[1941]: /usr/lib/colord/colord-sane: error while loading shared libraries: libsane.so.1: cannot open shared object file: No such file or directory

I installed the sane package just to squelch the error logging (can't remove colord, since gtk3 package depends on it):

# pacman -S sane
[...]
# pacman -Qo /usr/lib/libsane.so.1
/usr/lib/libsane.so is owned by sane 1.0.25-1

Error spam then disappears. I'd claim that the dependency should not be optional if the application constantly logs errors without it, which is why I'm filing this bug.

Alternatively we could go upstream to make colord better behaved in the absence of sane.

Additional info:
* package version(s)

# pacman -Q colord
colord 1.3.2-2

# pacman -Q sane
sane 1.0.25-1

* config and/or log files etc.

N/A

Steps to reproduce:

1. Install package colord without package sane.
2. Observe journalctl output.
