bug#25894: guix pull error

[rennes]

Hello,
in my situation the error was fixed with the command:
'guix gc --verify=contents'

The possible cause that generate the error is shutdown the machine 
unexpectedly.
Aditional my platform is Linux x86_64 with GuixSD version (20170302.02).

Thanks Leo, for helping with this.
