bug#37669: guile: warning: failed to install locale

[Jesse Gibbons]

On a GuixSD install, the following message began appearing today (I did not
record what time):
guile: warning: failed to install locale
It appears whenever I run `guix` regardless of the command-line arguments I
pass to it.
GUIX_LOCPATH looks like this:
~$ echo $GUIX_LOCPATH 
/run/current-system/locale
I have not today run "guix system reconfigure"
- Could this be related to the core-updates merge?
- Is there a work-around?
