d-bus command for bringing up buddy list

[infrabit at infrabit.net]

Switched from Kopete to Pidgin and I'm trying to set up a global shortcut to 
bring up the buddy list in KDE.

When I click on the tray icon to bring up the buddy list 'dbus-monitor' shows:

   signal sender=:1.107 -> dest=(null destination) serial=8364
      path=/im/pidgin/purple/PurpleObject;
      interface=im.pidgin.purple.PurpleInterface; member=GtkblistUnhiding
      int32 0

However this doesn't work:

   dbus-send /im/pidgin/purple/PurpleObject \
   im.pidgin.purple.PurpleInterface.GtkblistUnhiding int32:0


Any advice?
