[Mono-dev] MonoDevelop failure

[Kenneth D. Weinert]

I just upgraded to Ubuntu 8.04 and now have the following error when
trying to start up MonoDevelop:

System.TypeInitializationException: An exception was thrown by the type
initializer for MonoDevelop.Core.Gui.Services --->
System.InvalidOperationException: Extension node not found in path:

  at Mono.Addins.ExtensionContext.GetExtensionObjects (System.String

  at MonoDevelop.Ide.Gui.IdeApp.Initialize (IProgressMonitor monitor)

Any thoughts/hints/RTFMs?

Thanks.
