Probably the changes of Martin von Lowis. I imagine that when marcus is bad from holidays he can tell us more.
Now I try to reproduce it in 11128. I put a self halt in a method and execute the method. And I got no problem. After I tried to select 'self halt' + doit in the debugger itself and it worked too. Did you have a way reproduce it systematically ?
