What I understand is that an error occurs when trying to = show a hint to the user (display-hint in the backtrace)=2E This calls texi-= >plain-text which transforms texinfo markup to text for displaying on a = terminal=2E With your user name, it tries to read something like:

/h= ome/~a/=2Eguix-profile/etc/profile

Which is expanded into:

/h= ome/user@foo=2Ebar/=2Eguix-profile/etc/profile

And the @ is understo= od as texinfo markup but there is no @foo command in texinfo=2E How do we f= ix that though?
