What causes critical glib errors (when coding using messaging menu)?
- by fluteflute
If I run the python code below (almost entirely from this useful blog post) then I get three identical nasty looking error messages in the terminal. What might be causing them?
I note the number (5857 in the example below) changes slightly on each run. What does this number signify? Is it a memory location or something similar?
(messaging-menu.py:5857):
GLib-GIO-CRITICAL **:
g_dbus_method_invocation_return_dbus_error:
assertion `error_name != NULL &&
g_dbus_is_name (error_name)' failed
(messaging-menu.py:5857):
GLib-GIO-CRITICAL **:
g_dbus_method_invocation_return_dbus_error:
assertion `error_name != NULL &&
g_dbus_is_name (error_name)' failed

I'm running this on Natty, I should probably find out if I get the same errors in 10.10 though...

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")

# app from.
mm.set_desktop_file("/usr/share/applications/nautilus.desktop")
# Show the item in the MM.

# 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()
