it's about the float format LC_ALL is not needed, LC_NUMERIC is enough -
we are doing the following in uforadiant to prevent errors like these:

	/** @todo support system wide locale dirs */
	bindtextdomain(GETTEXT_PACKAGE, "i18n");
	/* set encoding to utf-8 to prevent errors for Windows */
	bind_textdomain_codeset(GETTEXT_PACKAGE, "UTF-8");

	gtk_init(&argc, &argv);

	/* reset some locale settings back to standard c
	 * this is e.g. needed for parsing float values from textfiles */
	setlocale(LC_NUMERIC, "C");
	setlocale(LC_TIME, "C");
