g_printerr() and related take an fprint() style format string as first parameter, followed by arguments for that fprint() format string – just a string was supplied here. As this function was only supplying a string, compilers would raise a format-security warning, which is commonly raised as an error (-Werror=format-security), stopping the compilation.
