My panel is gone, how do I get it back?
kquitapp plasma; rm $KDEHOME/share/config/plasma-appletsrc; plasma

This deletes your plasma settings, so you'll get the default 
configuration back. The panel-vanishing-on-crash issue was fixed just 
after 4.0.0's release. If running all the 3 commands at once doesn't 
work, try typing them in manually and wait a few seconds before running 
the next command.
