Ah, me #@!, I thought I tried that but I must have just tried
'unsigned'…

It doesn’t crash here (Debian Sid, it’s almost up to date with
the trunk). I use it for a org.freedesktop.Notifications and it
works great:

####
require 'Qt4'
app = Qt::Application.new([])
bus = Qt::DBusConnection.session_bus()
exit unless bus.connected?
msg = Qt::DBusMessage.create_method_call( 'org.freedesktop.Notifications',
                                          '/org/freedesktop/Notifications',
                                          'org.freedesktop.Notifications',
                                          'Notify' )
msg.arguments = [ 'Coucou', Qt::Variant.from_value( 0, "unsigned int" ),
                  'dialog-information', 'Title', 'blah', [], {}, -1  ]
rep = bus.call( msg )
if rep.type == Qt::DBusMessage
  puts "#{rep.error_name()}: #{rep.error_message()}"
end
####

It’s even quicker than with libdbus-ruby! (which uses
introspection)

Thanks a lot!

(Still, I can’t see a way for (u)int16 as there is not even a
 QVariant for shorts in C++. Or are DBus (u)int16 never used?)
