Yes, there is one node with a wrong checksum. On the internet I found 
[[https://forums.unraid.net/topic/92704-solved-btrfs-csum-error/][a matching 
topic on Unraid Forum]].

I checked RAM with Memtest (it passed) and then identified the
broken file.  So far, I think I got "lucky" and had a "cosmic ray"
kind of event - I do remember a single failure of resume-from-suspend some time 
ago.

I should be able to heal the system by deleting the bit-flipped
file and reinstalling gtk.  Does Guix have the ability to remove or
rewrite a specific file in its store?  The file is rooted in the
system configuration - not in a profile.

Thank you for your help.  I would also like to suggest a tweak to
the error message - to make the file system failure more obvious.
