I try to import Partner and his address, with GTK Client

i import successfully the res.partner CSV File

"ID","Name","Code"
2113,"RATP",7010700
2117,"CLEARSY",90222200

This import work succesfully, but when i try to import res.partner.address it fail with traceback

"ID","Street","Zip","City","Partner/ID"
