Comment(by zimmerma):

 Still there in 4.3.1:
 {{{
 sage: rational_reconstruction?
 ...

         exists, that pair is unique and this function returns it. If no
         such pair exists, this function raises ZeroDivisionError.
 }}}
 and:
 {{{
 sage: rational_reconstruction(29,105)
 ...
 ValueError: Rational reconstruction of 29 (mod 105) does not exist.
 }}}

 Note also that in 4.3.1 a.rational_reconstruction? gives a different
 documentation, which does
 not mention what happens in case of error. Why are the documentations
 different?
