Style/SymbolProc reports incorrect line for offense

[gotrevor]

The file:

[~/scratch/b] $ cat r.rb
[{ b: 1 }, { b: nil }].map { |element| element[:b] }
  .reject { |element| element.nil? }

Latest version of rubocop:

[~/scratch/b] $ rubocop -V

0.34.1 (using Parser 2.2.2.6, running on ruby 2.1.5 x86_64-darwin14.0)

Note that the line with the problem is line 2, not line 1, as reported below:

[~/scratch/b] $ rubocop -D r.rb

Offenses:

r.rb:1:1: C: Style/SymbolProc: Pass &:nil? as an argument to reject instead of a block.
[{ b: 1 }, { b: nil }].map { |element| element[:b] }
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Similarly, the fixing, though done properly, reports the wrong line as having changed:

[~/scratch/b] $ rubocop -D r.rb -a

Offenses:

r.rb:1:1: C: [Corrected] Style/SymbolProc: Pass &:nil? as an argument to reject instead of a block.
[{ b: 1 }, { b: nil }].map { |element| element[:b] }
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
