When I use gedit through the terminal (most recently for fstab modification), I get

What are these errors, why are they Critical, and how do I fix them? Gedit works still, so I have no idea what is going on.

Thanks,

How are you calling gedit? You should use:


gksudo gedit /etc/fstab

For graphical applications you should always use "gksudo" as opposed to "sudo".

I did:



me@my-computer:~$ gksudo gedit /etc/fstab

What is G_TYPE_CHECK_INSTANCE?

I get the same errors when I start emacs, not just gedit:

(emacs:18207): GLib-GObject-WARNING **: invalid (NULL) pointer instance

(emacs:18207): GLib-GObject-CRITICAL **: g_signal_connect_data: assertion `G_TYPE_CHECK_INSTANCE (instance)' failed

I'm using Ubuntu 10.04. Any idea what's going on?

I wouldn't care about those errors, as long as the respective app works. There are obviously a number of apps which cause the spewing of such -minor- error messages.
