Here’s one way to reproduce the bug, showing a crash in ‘display-hint’
due to an unescaped brace:
--8<---------------cut here---------------start------------->8---
$ mkdir /tmp/x{ample
$ touch /tmp/x{ample/guix.scm
$ (cd '/tmp/x{ample' ; guix shell)
guix shell: error: not loading '/tmp/x{ample/guix.scm' because not authorized
to do so
