Indeed, this comes from FreeBSD's Problem Report standards/150093:
    http://www.freebsd.org/cgi/query-pr.cgi?pr=150093

Getting the current system locale using the Standard Template Library
call, such as in
    std::cout << std::locale("").name() << std::endl;
throws the above runtime error.

You can still get it and set it using the clocale functions,
    char * systemLocale = std::getenv("LANG");
    std::setlocale(LC_ALL, systemLocale);
or simply
    stdlocale(LC_ALL, "") as tudu currently does.
but you can't use that to set up ifs.imbue(), ofs.imbue() and
file.imbue() because of the above problem.

However, those don't seem to be really necesary on Mac OS X, whose
console uses UTF-8 as default.
I modified the files interface.cc, parser.cc and config.cc catching those calls:
        try {
                file.imbue(locale(""));
        } catch (runtime_error& err) {
                // PR 150093
        }

This way, tudu mostly works on Mac OS X, but has a problem when
reading the XML file next time, not interpreting the encoding
correctly (vim does).
I guess there is a bug there.
