Thank you for the valgrind log Brett, it pointed to the problem: ==10469== Use of uninitialised value of size 4 ==10469== at 0x8057108: on_essid_list_changed (connection.c:200) ==10469== by 0x80579BD: connection_dialog_prepare (connection.c:236) ==10469== by 0x80563FB: on_iface_properties_clicked (callbacks.c:58) ==10469== by 0x49259B8: g_cclosure_marshal_VOID__VOID (in /usr/lib/libgobject-2.0.so.0.1200.7)
Upstream is fixing the crasher now. Do you have any essid listed if you use "iwlist scanning"? ** Changed in: gnome-system-tools (Ubuntu) Status: Needs Info => Fix Committed -- Network Admin crashes when trying to edit the Wireless Network's Properties https://launchpad.net/bugs/76174 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
