error when changing settings in wicd-gtk. wicd-daemmon.py

Hi!
I tried to update wicd (to 1.7.2.4) on my laptop running Linux Mint. I first struggeled some with an error in the installing (due to ast.po), but finally got it installed with no errors. Now the problem is that I can't seem to be able to configure wicd from gtk (or curses for that matter). I keep on getting the error:

Traceback (most recent call last):
  File "/usr/share/wicd/gtk/netentry.py", line 945, in update_autoconnect
    noneToString(self.chkbox_autoconnect.
  File "/usr/lib/pymodules/python2.7/dbus/proxies.py", line 140, in __call__
    **keywords)
  File "/usr/lib/pymodules/python2.7/dbus/connection.py", line 630, in call_blocking
    message, timeout)
dbus.exceptions.DBusException: org.freedesktop.DBus.Python.TypeError: Traceback (most recent call last):

    retval = candidate_method(self, *args, **keywords)
  File "/usr/share/wicd/daemon/wicd-daemon.py", line 1067, in SetWirelessProperty
    prop = misc.sanitize_config(prop)
  File "/usr/local/lib/python2.7/dist-packages/wicd/misc.py", line 433, in sanitize_config
    return s.translate(None, table)
TypeError: translate() takes exactly one argument (2 given)

On some forums I read that some fixed this error by changing

       prop = misc.sanitize_config(prop)
to
       prop = misc.sanitize_config(str(prop))

But this had no effect for me. Any help would be much appriciated:)
