wxpython and telnet newbie

[ataraxia2500]

I found that little howto on the wxpython wiki: http://wiki.wxpython.org
index.cgi/WxHowtoSmallTelnetClient
I copied the whole thing and past it as is then I tried to run it but I got
an error. 
this is the error message I got:


/usr/share/themes/Geramik/gtk-2.0/gtkrc:25: error: unexpected identifier
`GtkButton', expected character `}'
Traceback (most recent call last):
  File "wxtelnet.py", line 70, in ?
    frame = TelnetFrame(None, -1, sys.argv[1])
IndexError: list index out of range




maybe I should modify some lines, I'm not sure.

thanx in advance
