[not CCing to r-bugs, because quite probably not a bug ...]

He? Why does MASS load when you try to load a workspace?

Anyway, it sounds like you have mixed different R installations (in 
particular one that is older than R-1.9.0 and R-1.9.1) or at least you 
have outdated packages in your libraries.
Moreover, you may have some self edited startup stuff (like loading 
MASS in any RProfile file???).

It would help us to know what you did exactly ...
