This problem has been fixed on the soon-to-be-merged 'core-updates'
branch.  Pulling that branch should be safe as no big rebuilds are
scheduled at this point, and you get to help out Guix development by
testing it!

To get it, use 'guix pull --branch=core-updates' or adjust your
channels.scm.

If using "core-updates" is impractical, you can work around this issue
in the meantime by adding (list glib "bin") in the 'packages' field of
your operating-system declaration.

HTH!
