gnome-do crashes on start with unhandled exception

[Markus]

Binary package hint: gnome-do

On Ubuntu 10.04 LTS Lucid Lynx, "gnome-do 0.8.3.1+dfsg-1ubuntu1" crashes on start with an unhandled exception:

$ gnome-do

Unhandled Exception: System.InvalidOperationException: Extension node not found in path: /Do/Service

After deleting ~/.local/share/gnome-do/plugins I get additional warnings and errors about different assemblies not being found:
