Error building with guix system image

Running `guix system image image-minimal.scm` fails with the following
build log:

```build log for partition.img.drv

registering 337 items | [progress bar animation, fails before end]

Does anyone have any pointers on how to debug or fix this? The operating
system builds nicely with `guix system vm`. Building
`gnu/system/examples/bare-bones.tmpl` with `guix system image` also
fails with a similar error and works correctly with `guix system vm`.


```image-minimal.scm
(use-modules
  (gnu)
  (gnu system image))

(define %operating-system
  (operating-system
   (host-name "image-test")
   (bootloader (bootloader-configuration
                (bootloader grub-bootloader)
                (targets '("/dev/sdX"))))
   (file-systems (cons*
                  (file-system
                   (mount-point "/")
                   (device "/dev/sdX1")
                   (type "ext4"))
                  %base-file-systems))))

(image-with-os (raw-with-offset-disk-image)
               %operating-system)
```

Output of `guix describe` just in case, though the error also occured
with the latest guix version when I tested.

```channels.scm

        (name 'guix)

Do you correctly substitute /dev/sdX for your real device name (e.g.,
/dev/sda) ?

It should print a nice error when it doesn't exist, I think, but perhaps
it regressed.

'guix system vm' overrides the root file system, so wouldn't complain
about a problem in your root file system definition.

I did try with that too, but it failed with the same error. Today I
almost accidentally found out that this error was caused by a corrupt
store item and was fixed by running `guix gc --verify=contents,repair`.

The error message could certainly be improved (or rather, a error
message about a corrupt store could be added), but I didn't find the
actual failing check so that I can't send a patch.

OK!  I'm glad you at least got past that road bump.
