what about to fix it this way: isPostMortem "return whether we're inspecting a frozen exception without a process attached" |selectedContext suspendedContext | selectedContext := self selectedContext. suspendedContext := interruptedProcess suspendedContext. suspendedContext ifNil: [ ^ false ]. (suspendedContext == selectedContext) ifTrue: [ ^ false ]. ^ (suspendedContext findContextSuchThat: [:c | c sender == selectedContext]) isNil -- Pavel On Tue, Mar 6, 2012 at 12:08 PM, Stéphane Ducasse <stephane.ducasse@inria.fr> wrote:

Hi guys

when I try to load

MCSqueaksourceRepository        location: 'http://squeaksource.com/Games'        user: ''        password: ''

load MorphicGames-md.1.mcz

I get a DNU

isPostMortem        "return whether we're inspecting a frozen exception without a process attached"        |selectedContext|        selectedContext := self selectedContext.        (interruptedProcess suspendedContext == selectedContext)                ifTrue: [ ^ false ].        ^ (interruptedProcess suspendedContext findContextSuchThat: [:c | c sender == selectedContext]) isNil

                                                                       ^^^^^^ DNU findContextSuchThat:

interruptedProcess suspendedContext is a MethodContext

Now I do not understand since find findContextSuchThat: is defined in ContextPart the super class of MethodContext.
