O que causa erros críticos (ao codificar usando o menu de mensagens)?

Question

Se eu executar o código Python abaixo (quase totalmente este útil post no blog então eu recebo três mensagens de erro idênticas e desagradáveis no terminal. O que pode estar causando isso?

Eu observei que o número (5857 no exemplo abaixo) muda um pouco em cada execução. O que esse número significa? É um local de memória ou algo similar?

  

(messaging-menu.py: 57857):   GLIB-GIO-CRÍTICO **:   g_dbus_method_invocation_return_dbus_error:   assertion 'error_name! = NULL & amp; & amp;   g_dbus_is_name (error_name) 'failed

     

(messaging-menu.py: 57857):   GLIB-GIO-CRÍTICO **:   g_dbus_method_invocation_return_dbus_error:   assertion 'error_name! = NULL & amp; & amp;   g_dbus_is_name (error_name) 'failed

Eu estou rodando isso no Natty, eu provavelmente deveria descobrir se eu recebo os mesmos erros em 10.10 ...

import gtk

def show_window_function(x, y):
    print x
    print y

# get the indicate module, which does all the work
import indicate

# Create a server item
mm = indicate.indicate_server_ref_default()
# If someone clicks your server item in the MM, fire the server-display signal
mm.connect("server-display", show_window_function)
# Set the type of messages that your item uses. It's not at all clear which types
# you're allowed to use, here.
mm.set_type("message.im")
# You must specify a .desktop file: this is where the MM gets the name of your
# app from.
mm.set_desktop_file("/usr/share/applications/nautilus.desktop")
# Show the item in the MM.
mm.show()

# Create a source item
mm_source = indicate.Indicator()
# Again, it's not clear which subtypes you are allowed to use here.
mm_source.set_property("subtype", "im")
# "Sender" is the text that appears in the source item in the MM
mm_source.set_property("sender", "Unread")
# If someone clicks this source item in the MM, fire the user-display signal
mm_source.connect("user-display", show_window_function)
# Light up the messaging menu so that people know something has changed
mm_source.set_property("draw-attention", "true")
# Set the count of messages in this source.
mm_source.set_property("count", "15")
# If you prefer, you can set the time of the last message from this source,
# rather than the count. (You can't set both.) This means that instead of a
# message count, the MM will show "2m" or similar for the time since this
# message arrived.
# mm_source.set_property_time("time", time.time())
mm_source.show()

gtk.main()

Testes no Maverick sugerem que isso é um bug do Natty, então eu relatei um bug .
