[network-admin] bug with several location in System->Networking (network-admin)

I have been install Ubuntu 6.06 LTS from skretch.
At work my ip address is 192.168.0.12
I have been use network-admin(Сетевые настройки) for configure it. Yes, default language is RUSSIAN, locate - UTF-8.

I selected network-admin form system menu.
Than, in network-admin i select "Create Location" (Создать новое расположение"), enter name "xring" in ENGLISH.
Than i click ETHERNET, PROPIERTIES, and enter ip, gataway, mask,
than i enter DNS.
OK.
ALL work fine. IN file /etc/network/interfaces

CLOSE NETWORKING.

I GOTO TO MY WORK. booting, current ip adress 10.33.24.58, i launch SYSTEM->Networking, select "xring", current ip 192.168.0.1
ALL WORK FINE.
BUT AT HOME when i select "moscow_home" current ip address still was 192.168.0.1, i lick OK, i lauched Networking again, location field was blank, i select "moscow_home", click PROPERTIES, and ip address was 192.168.0.1 and ather field the same with "xring" WHYYY???????
ifconfig shows wrong ip.
I reenter all field in "moscow_home" click ok.
ifconfig shows right ip.
I restart System->Networking (network-admin). I see blank location (current location is blank), i select moscow-home, and get wrong ip. Again all setting getting from "xring".
I remove "xring", reenter all "fields" in "moscow_home",
click OK, ifconfig shows right ip.
RELAUNCH network-admin, select "moscow_home" --- wrong setting, all settin from "xring", BUT it removed.
I see at /etc/gnome-system-tools/network/profiles.xml
