It seems this was broken by f409dd48
(https://bugzilla.gnome.org/show_bug.cgi?id=755019). An indentation
change removed the G_GNUC_PRINTF macro that was silencing this
warning. This is only visible on clang because only clang applies the
-Wformat-nonliteral flag to function definitions that take va_list
arguments.
