bug#51114: Owncloud client error message

[Cayetano Santos]

Context:

Using guix as a package manager under a foreign, up to date 
archlinux distribution.

Problem:

When I install owncloud-client, and provide the log in 
credentials, I get a message

 "could not read system exclude file"

I have to notice that, when I’m using archlinux provided package, 
all works as expected.

Thanks,
