This was helpful. It may be good to explain the syntax of the error 
message is

line.column - line.column and the second line is omitted if it does not 
change. I was too stupid to realize that.

I am not sitting on this version of th lens:

http://pastie.org/749121

and get this error when I try and parse:

Test run encountered exception:
cobblersettings.aug:50.11-53.31:exception: overlapping lenses in tree 
union.put
     Example matched by both:  {  }
     First lens: cobblersettings.aug:50.11-52.42
     Second lens: cobblersettings.aug:48.29-.102


If I change line 49 slighlty (remove hte outer lens)


http://pastie.org/749238

I get this:

cobblersettings.aug:50.11-53.31:exception: overlapping lenses in tree 
union.put
     Example matched by both:  { "value" = "''" }
     First lens: cobblersettings.aug:50.11-52.42
     Second lens: cobblersettings.aug:48.29-.100


I think I am close.. I am just missing something basic I think.
