dbus error

[Germán A. Racca]

Hi list:

I have downloaded a program from gnome-look[1] and I get the following
error in F12 x86_64:

[german at centauri bin]$ python twl
starting viewer process
ERROR:dbus.connection:Unable to set arguments (None,) according to
signature u'v': <type 'exceptions.TypeError'>: Don't know how which
D-Bus type to use to encode type "NoneType"
Traceback (most recent call last):
  File "twl", line 25, in <module>
    twl.main()
  File "../twl/main.py", line 526, in main

  File "../twl/main.py", line 124, in __init__
    self.Preview.set_metacity_theme(self.m_theme_name)
  File "/usr/lib/python2.6/site-packages/dbus/proxies.py", line 68, in

in call_blocking
    message.append(signature=signature, *args)
TypeError: Don't know how which D-Bus type to use to encode type

Any help is welcome!
