It looks like some "Failed magic" is involved here. A bit of the stack for your viewing pleasure: MessageNotUnderstood: receiver of "ifTrue:ifFalse:" is nil UndefinedObject(Object)>>doesNotUnderstand: #ifTrue:ifFalse: STONWriter>>ExecuteUnOptimizedIn: UndefinedObject(Object)>>mustBeBooleanInMagic: UndefinedObject(Object)>>mustBeBoolean STONWriter>>encodeString: Perhaps this is a Pharo6.0 bug -- triggered by my bug in STONWriter>>encodeString: Travis is running headless and presumably the error/notification/exception handling is a bit different running headless?

I am trying to debug a problem that showed up loading my version of STON into Pharo-6.0. ON Travis, I see the error message[1]:
MessageNotUnderstood: receiver of "ifTrue:ifFalse:" is nil
The code is loading and passing tests in Pharo-5.0, 4.0, 3.0 and several versions of GemStone, so I am interested in bringing up a debugger...
I cloned git@github.com:GsDevKit/ston.git and checked out the gs_port branch into the directory /export/foos1/users/dhenrich/dev/_home/server/stones/m_340/git/ston.
But when I run the following code in a Pharo-6.0 image using the Playground by pressing the green arrow:
Metacello new baseline: 'Ston'; repository: 'gitfiletree:///export/foos1/users/dhenrich/dev/_home/server/stones/m_340/git/ston/repository'; load: #( 'UTF8' 'Tests')
I do not get the expected MNU in a debugger -- but I do see a bunch of infos popping up during the execution but they fade too quickly for me to actually read them --- there were 8 or more popups --- and I got the impression that they involved the ifTrue:ifFalse:, but danged if I know how to debug the problem ...
I must have missed the memo that tells me how to get a debugger up in Pharo-6.0 ...
Any advice?
