Comment 2 for bug 210023

I have similar problems with other arguments. For example:

$ listen --next
location: /usr/lib/xulrunner-1.9b5/libxpcom.so
before 3
Traceback (most recent call last):
  File "/usr/lib/listen/listen.py", line 218, in <module>
    ListenApp()
  File "/usr/lib/listen/listen.py", line 150, in __init__
    option.run_load(bonobo_client)
  File "/usr/lib/listen/option_parser.py", line 81, in run_load
    ret = client.msg_send("control",("next",""))
AttributeError: 'NoneType' object has no attribute 'msg_send'

$ listen --previous
location: /usr/lib/xulrunner-1.9b5/libxpcom.so
before 3
Traceback (most recent call last):
  File "/usr/lib/listen/listen.py", line 218, in <module>
    ListenApp()
  File "/usr/lib/listen/listen.py", line 150, in __init__
    option.run_load(bonobo_client)
  File "/usr/lib/listen/option_parser.py", line 84, in run_load
    ret = client.msg_send("control",("previous",""))
