[libSoup 2.44] : MacOsX => build fails by soup-logger.c because of g_strdup_vprintf

[Hugo Machefer <hugo machefer gmail com>]

Dear libSoup mailing-list.

Allow me to refer to logs by http://clang.debian.net/logs/2013-07-14/libsoup2.4_2.42.2-6_unstable_clang.log

Reminder :

soup-logger.c:377:27: error: format string is not a string literal [-Werror,-Wformat-nonliteral]
        data = "" (format, args);
                                 ^~~~~~

How have this (recent) issue been solved ? 

Observing similar symptoms by compiling libSoup 2.44 for MacOSx.

Thanks in advance for your precious support.

Regards.

Hugo
