The problem is that the “activation scripts” run in the C locale and
thus Guile interprets file names in this locale encoding (i.e., ASCII),
which fails.

I believe the attached patch mostly fixes the problem.  Could you try
and report back?

I say “mostly” because if /tmp contains a file in an encoding other than
that of the system locale, we still have a problem.

Once we’ve switched to Guile 2.2, we should probably force use of an
ISO-8859-1 locale to avoid file name decoding altogether.

Thanks,
Ludo’.
