inclusive_end does not work as expected

On behalf of Marco Monteiro;

I expected both of the following queries to return the result of the first one.
The difference betwen the two queries is the inclusive_end argument.

ruby-1.9.2-p0 > db.view("calculate/work_duration_by_project_id_and_start_time", :group_level=>2, :startkey => ["0da7979149f2d71f1f5c2361c400c8f2", "2000"], :endkey => ["0da7979149f2d71f1f5c2361c400c8f2", "2011"], :inclusive_end=>true)["rows"].each do |r| puts r end; nil

{"key"=>["0da7979149f2d71f1f5c2361c400c8f2", "2000-03-01 00:00:00"], "value"=>12340} {"key"=>["0da7979149f2d71f1f5c2361c400c8f2", "2010-10-19 23:00:00"], "value"=>8400} {"key"=>["0da7979149f2d71f1f5c2361c400c8f2", "2010-10-24 23:00:00"], "value"=>12900} {"key"=>["0da7979149f2d71f1f5c2361c400c8f2", "2010-10-28 23:00:00"], "value"=>70975}

All other agruments being equal, I expect a query with inclusive_end set to true to never return less rows than one with inclusive_end set to false.
Am I missing something?

I have checked the request made by the CouchRest library (this could be a CouchRest bug), and the request url is as expected.
