Reproducible: Always

Steps to Reproduce:
1.Create a dsf launch to debug some simple program
2.Add one memory monitor and see the contents rendered in memory view
3.Now finish debugging either by terminate or running to end the program
4.Bring the  Memory view to the top and you will see memory monitor is still there and an Exception is thrown
