Beth,
I thought that error was reproducible - but I just opened the workspace without hitting this error.....Ok, I had to retry a couple of times (open workspace - close - open - run an X10 program that got an error - close - open - boom !! - clear log - close - open -boom again !!). Means, it is isn't reproducible at every opening of a workspace. I am not missing any particular view in any perspective after the error is flagged.
As for the X10DT version, is this what you are looking for ?

Christoph, what were you doing when this happened?
Sometimes if you open a workspace after installing something different in eclipse or open it with a new eclipse installation, it's just telling you that the view you had before isn't there any more. It's not necessarily a bug.
Was everything ok after you either restored the perspective, or it did that itself?
