* gnome/applet/applet-compat.c - Fix bugs in GConf entry conversion * gnome/applet/applet-dbus-info.c - (nmi_dbus_get_network_properties): handle case of the BSSID list being zero-length * libnm-util/cipher-* libnm-util/dbus-helpers.c - All ciphers must now return hashed keys as UTF-8 valid hexadecimal strings, ie "8f3dae4023". They are pushed through dbus as strings too. - Consolidate various functions that do bin->hex and hex->bin conversion into cipher.c * src/nm-ap-security-wep.c src/nm-ap-security-wpa-psk.c - Handle NULL keys since we may not know keys right away * src/nm-dbus-nmi.c - (nm_dbus_get_network_data_cb): actually advance to the start of the wireless security info before we try to deserialize it * libnm-util/test-ciphers.c - Update cipher tests for the change to UTF-8 hexadecimal strings git-svn-id: http://svn-archive.gnome.org/svn/NetworkManager/trunk@1230 4912f4e0-d625-0410-9fb7-b9a5a253dbdc
