Well now, you're correct.

Not sure why this is coming up though.

Paul, who is the working set ninja?

I have not quite found the smoking gun here, but it's looking like a CNF problem.  The problem is the WorkingSet contains the PDE object that corresponds to a project (and it properly adapts to said project).  This is the object in the CommonViewer.  The CNF is getting confused and not properly finding the correct navigator contribution descriptor corresponding to this object, instead it finds the working set contribution descriptor and asks it for the label of the PDE object which of course it can't provide.

This seems like a pretty serious problem, it's going to take me a bit longer to figure it out.

Could the Mylyn/Tasks be affecting this also?

It's possible, I'm not sure, hopefully I should be able to look into this more in the next week or so.

The fix for 212389 makes this problem go away.
