 {{{

 In 2.1.8 I get:


 {{{
 BOX(-71.7821 42.2622088907314,-71.0289871125841 42.9067128874151)
 }}}


 In 2.2.0 I get:


 {{{
 BOX(-71.7821 42.2622088907314,1.17549435082229e-038 42.9067128874151)
 }}}

 I'm very concerned about that - 1.17549435082229e-038   that seems to have
 come out of no where
