After a few restarts of MonoDevelop (without installing or removing anything), I was able to enable the updated D add-in.

So after all, it's working?

Yes, it's working now. I don't know what could be the reason that it refused to enable the add-in before.

I had exactly the same problem on Archlinux, MonoDevelop 5.10. I got that Exception on the update and couldn't enable the addon anymore. Even deleting the addon, manually removing it from .local etc didn't help. In the end I deleted .config/MonoDevelop .config/MonoDevelop-5.0 .cache/MonoDevelop-5.0/ .local/share/MonoDevelop-5.0, reinstalled the addon and reconfigured MonoDevelop. Now everything is working as expected.
