GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed

[Andrew Melo]

Binary package hint: network-manager

When starting NM, the following is spammed to the console.

GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed

amelo@amelo-laptop:~$ dpkg --list | grep network | grep manager

I also confront this problem, as I start nm-applet in a terminal, the following lines appear on my term:

sao3@sao3-laptop:~$ sudo nm-applet

** (nm-applet:7197): WARNING **: <WARN> applet_dbus_manager_start_service(): Could not acquire the NetworkManagerUserSettings service as it is already taken. Return: 3

[Stu Zhao (sao3)]

mine is cause by a existing nm-applet, however, the network-manager failed to display an icon in the task bar, and I thought it's not started.

sao3, your bug and the evaluation for your issue is in bug 289466

[Alexander Sack (asac)]

pretty harmless. we need a backtrace with symbols of that critical output to proceed

[Stu Zhao (sao3)]

Alex: Oh, i see, thanks.

[Alexander Sack (asac)]

anyone can still reproduce this particular critical issues and can get a backtrace with debug symbols?

I received the error not on network-manager, but when firefox is running and the yahoo.com page is opening.
here is what I did:
- launched firefox 3.0.9 from terminal under ubunut 8.10
- in browser address bar, enter www.yahoo.com
then you will see under terminal

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Oneiric Ocelot. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your help.
