[Users] ovirt-shell can not connect

Hi, I can not connect to the ovirt-shell. When I type: ovirt-shell -c I get the following message: error: __init__() got an unexpected keyword argument 'validate_cert_chain' my .ovirtshellrc is: [ovirt-shell] username = admin@internal url = https//127.0.0.1:443/api insecure = False filter = False timeout = -1 dont_validate_cert_chain = False password = xxxxx I'm using the rpm package: ovirt-engine-cli-3.2.0.10-1.el6.noarch Has anyone an idea? The GUI login works. Thanks, Michael
