Concerning this error,
(Did a synaptic system update, I have E17, with kde installed for opera and k3b,
and now at startup there is an error,
"Couldn't recognize the image file format for file
/usr/share/gdm/themes/PCLinuxOS-Obsidian-2/background.jpg)
I powered off twice, once after reinstalling kde4, and then again after removing it. Oddly, after posting here last night, when I started
up this morning, I went to fetch some coffee, and came back to see the E17 desktop ready for action!

So I logged out, and
logged back in, and the error shows up. I let it sit a few minutes to insure it was not a timing issue, then logged in at the
'standard greeter'. I then powered off, and rebooted, and again, the desktop loaded normally. The odd widget/icon/permissions
issues remain.

also, dbus-launch nautilus as user fails, and yields this terminal output:

but dbus-launch nautilus as root, starts fine, with this terminal output:
** Message: Initializing gksu extension...
Initializing nautilus-image-converter extension
Initializing nautilus-gdu extension
and when nautilus is closed, adds this
** (nautilus:22326): WARNING **: Unable to add monitor: Not supported
sys:1: GtkWarning: IA__gtk_container_foreach: assertion `GTK_IS_CONTAINER (container)' failed
Also, when closing any gnome-terminal, I get an error:
"Enlightenment was unable to run the application: gnome-terminal
The application failed to start"
