Debug Expression could not be evaluated

 

In Debug when i select a variable to Add to Watch i get the messages Expression could not be Evaluated.

How can i solve this?

 
Something inside the expression could not be determined properly by terminal. Please give steps to reproduce as to see it is a bug or not.
