When I boot, I often encounter this warning. How can I get rid of this?

The panel encountered a problem while loading "IndicatorAppletFactory::IndicatorApplet". Do you want to delete the applet from your configuration?

I use ubuntu 11.04.

In $HOME/.xsession-errors, the following part seems to be relevant.

Initializing nautilus-gdu extension

(nautilus:1490): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed

** (gnome-panel:1493): WARNING **: Failed to load applet IndicatorAppletFactory::IndicatorApplet:

Which indicator applet does the system want to remove from your configuration? – Kory Wnuk Jun 3 '11 at 22:19
@Kory It doesn't say in particular. But all I have is System Monitor, Indicator Applet, and a few launchers. – sawa Jun 3 '11 at 22:22
Has this error been noticed since you began using Ubuntu 11.04, or have you added some indicator applets recently? – Kory Wnuk Jun 3 '11 at 22:26
It is since I began using Ubuntu 11.04. It seems to be a common problem, as I see other people reporting the same thing, but I cannot find a solution. – sawa Jun 3 '11 at 22:28
If you were to view the contents of $HOME/.xsession-errors, is there any indication of what might have gone awry? – Kory Wnuk Jun 3 '11 at 22:43

go to your home folder

press ctrl + h

then your home folder will display hidden files

check whether any of the folders is locked

right click on the folder then click "properties". In that Click "permissions".

In owner, change folder access to "create and delete files."

And then click "Apply Permissions to Enclosed files"

If you cannot see any locked folders then select all folders and do the above
