Regression in 4.5 M5: during debugging, on stepping through the code, outline view shows time to time error dialog with the stack below. I never seen it before. 4.5 M4 was OK.

During debugging I have Outline hidden and behind the variables view, but for whatever reasons it tries to update itself and throws the exception below.
