wicd-cli does not switch wired network profiles

wicd version 1.7.0 from debian squeeze repos

Switching with command:
wicd -z -o -m wired-default does not work and gives this error:

Traceback (most recent call last):
  File "/usr/share/wicd/cli/wicd-cli.py", line 99, in <module>

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod: Method "ReadWiredNetworkProfile" with signature "s" on interface "org.wicd.daemon.config" doesn't exist

The problem is in wicd-cli.py line 99:
Instead of
config.ReadWiredNetworkProfile(options.name)
it should read
wired.ReadWiredNetworkProfile(options.name)
