Comment 23 for bug 1308348

Same here with xfce and 14.04
nm-applet is shown as running process (ps ax), but no icon is shown.
Starting it with sudo (sudo nm-applet) make the icon appear.

INHO: Since it affects several distributions, the affected packed should be changed to "nm-applet" and not "lxpanel", hence the same issu doesn't need to have the same bug-report just with other distributions and panel-packages
