More Plasma. Testcase:

require 'korundum4'
require 'plasma_applet'

about = KDE::AboutData.new(
'ruby_kapp', # app internal name
'ruby_kapp', # translation catalog name
KDE.ki18n( 'Ruby KApp' ), # name to be displayed
'1.8.7', #version
KDE.ki18n( 'Kuick IRB Application' ), #description
KDE::AboutData::License_GPL_V3, #license
KDE.ki18n( '(c) 2010 Matz ja nai' ) # copyright statement
                            ) #AboutData
KDE::CmdLineArgs.init(ARGV, about)
KDE::Application.new

puts "list installed applets"
puts Plasma::Applet::listAppletInfo #crash

==========================
By the way, the Plasma bindings can be used outside Plasma applets. Should the 
bindings be renamed to 'plasma' and 'plasma_applet' kept as an alias?
