nm-applet is removed from panel just after start of applet

[Andcor]

Hi
After an update of my Xubuntu laptop to 12.4 from 11.10 I have not seen the nm-applet. It is not in the panel when I start the PC, even though the nm-applet process is running.
I have tried stopping the process and restarting from terminal to see the error output, but it doesn't make any sense for me:

** Message: applet now removed from the notification area
** Message: applet now embedded in the notification area
** Message: applet now removed from the notification area

(nm-applet:4449): GdkPixbuf-CRITICAL **: gdk_pixbuf_scale_simple: assertion `dest_width > 0' failed
** Message: using fallback from indicator to GtkStatusIcon

(nm-applet:4449): GdkPixbuf-CRITICAL **: gdk_pixbuf_scale_simple: assertion `dest_width > 0' failed

The Last line is repeated until I press ctrl+c which then writes a couple of lines:

^C** Message: PID 0 (we are 4449) sent signal 2, shutting down...
** Message: moving back from GtkStatusIcon to indicator

(nm-applet:4449): Gtk-CRITICAL **: gtk_status_icon_set_visible: assertion `GTK_IS_STATUS_ICON (status_icon)' failed

The network manager correctly connects to the networks defined, but I cannot control which connections should be active and switch between my eth0 connections.

I hope that you can help me.

Status changed to 'Confirmed' because the bug affects multiple users.

Hey,
I have the same problem here.. But not with XUbuntu..
I did a fresh install using the command-line option (in the alternate CD), then I installed MATE Desktop, now I have the same error when trying to start nm-applet.

For me I find the solution, I need to delete the content of /etc/network/interfaces (or just leave the lo interface in it).. After that nm-applet will be able to administrate the nic interfaces.
