[Pharo-project] Error loading update with AnObsoleteTranscript

[Alain_Rastoul]

Hi,

Trying to upgrade my 1.3 image with Menu/System/Software Update,
I had a MNU during update 13191 at
AnObsoleteTranscript class >> cr
which comes from:
UndeclaredVariableWarning>>defaultAction
 selector ifNotNil: [Transcript cr; nextPutAll: class name, '>>', selector, 
' ']
   ifNil: [Transcript cr ].
 Transcript show: '(' , name , ' is Undeclared) '.
 ^true

Something is missing or I did something wrong?

TIA
Regards,
Alain
