Subject: 2003-04-12  Havoc Pennington  <hp@pobox.com>

	* bus/config-parser.c (bus_config_parser_new): fix a memleak

	* dbus/dbus-sysdeps.c: change DBusCredentials to use longs for
	the pid/gid/uid, just for paranoia.

	* test/break-loader.c (randomly_do_n_things): find a byte
	containing a type code, and randomly change it to a different
	type code.
