Calculations not working [betty 1.6]

[hotice]

I've upgraded to Betty 1.6 and the new calculations feature doesn't work:

$ betty what is 40 plus 2
Betty: Running bc <<< 40+2
sh: 1: Syntax error: redirection unexpected

However, if I type the command that Betty is supposed to run, it works:

bc <<< 40+2
42

I'm using Ubuntu 14.04 / bash 4.3 / ruby 1.9.3.4.

I found the problem : Betty uses sh, not bash, and "<<<" is not supported by sh. It works fine after replacing with : echo 'expr' | bc

Should this issue still be open? It's working for me on 1.8. though it does not show what command it is running, just the answer.
