How to be able to get a debugger inside DNU

Hi,

I am not quite sure where the issue is because I cannot seem to reproduce the problem.

I try this Playground script:

Object subclass: #ABC
        instanceVariableNames: ''
        classVariableNames: ''
        package: 'ABC'.

ABC compile: 'doesNotUnderstand: aMessage
        "support sending message to access properties"

        | selector |
        selector := aMessage selector.
        self halt: aMessage selector.
        ^ selector isUnary
                ifTrue: [ (self hasPropertyAt: selector)
                                ifTrue: [ self propertyAt: aMessage selector asSymbol ]
                                ifFalse: [ super doesNotUnderstand: aMessage ] ]
                ifFalse: [ selector numArgs = 1
                                ifTrue: [ self propertyAt: aMessage selector allButLast asSymbol put: aMessage argument ]
                                ifFalse: [ super doesNotUnderstand: aMessage ] ]'.

ABC new bla.



And I get a debugger. What am I missing?

Cheers,
Doru

“Live like you mean it."

In fact my test was broken an in addition the debugger does not show the top frame and it took me a while to see that I 

should always scroll to be the stack. 

And I was always only seeing this mustBeABoolean.

I also have to scroll up to see the last frame (Pharo 5.0).
