[Pharo-project] Bug while updating PharoCore

[Casimiro de Almeida Barreto]

While loading 13171-Pha-CleanupsFinderSearch debugger is raised with
Message not understood: Receiver of "load" is nil

and:

DoIt
    | t1 |
    t1 := MCHttpRepository
                location: 'http://www.squeaksource.com/Pharo/'
                user: ''
                password: ''.
    (t1 loadVersionFromFileNamed: 'ScriptLoader13-MarcusDenker.191.mcz')
load.
    ^ ScriptLoader new update13171

Meaning ScriptLoader13-MarcusKender.191.mcz is not there or squeaksource
is down...
