I have encountered the same error. It seems to recur for me after major updates.
So there seems to be something lurking to reawaken the real error message 
source.
I collected some symptoms and posted them as bug#37900.

I hope it will be obvious to someone what is happening, so this nuisance
can be eliminated (and everyone will be relieved of hearing about it repeatedly 
:)
(if I am doing something dumb for my case, I promise to try to avoid repeating 
:)

When you were getting the error message from guix commands (which apparently
uses guile in a way that causes _guile_ to complain),
were you also getting the same error message when invoking guile directly?

I was not -- please see #bug37900 for my attempt to explore the difference.

Me too. I think guix can be great, though my user experience
is not quite great yet :)
