I added a favicon.ico to the imageDirectory and put:

locator at: (ALPath / 'favicon.ico')
             put: (ALFileResource on: (FSLocator imageDirectory / 
'favicon.ico'))

into #initializeLocator.

The favicon.ico missing error is gone. It's replaced with FSLocator 
stumbling on something. Did I miss a step?
