This problem affects both testing and unstable with 3.0.9 and 3.0.10. Feel free to raise level if appropriate,
because it causes multiple problems even in third-party modules.

This seems not a guile issue but a pure Debian one, the guix version
works for instance. Note that this does not affect stable.

Bah, sorry for the noise, that's due to missing generated locales, which
needs to be considered in code.

Hmm.  Perhaps check (if you haven't already) that the locales package is
installed and that locale is enabled (e.g. via dpkg-reconfigure
locales).  Oh, or actually, "locale -a" may be a sufficient check.

Thanks

Yep, I had to generate the required locale via dpkg-reconfigure, which in general
is a bit a pain because some modules have tests done with specific
locales which fail, that was the origin of the report... Probably should be
considered a non-issue.

Ok, I *think* this issue could be converted in an upstream one, about
documentation. Note that make-locale reports:

"A system-error exception (see How to Handle Errors) is raised by
make-locale when locale-name does not match any of the locales compiled
on the system. Note that on non-GNU systems, this error may be raised
later, when the locale object is actually used."

while setlocale section does not report anything about that.
