It goes a bit further with this.

When I try it without debug, It fails right at the start  (the scanner 
does nothing).

With debug, I hear the scanner trying to scan. Then it fails with what 
seems to be the usual error. But I still hear it do some work, so it 
seems better (but I still can't scan :) )
