Bug: using as function with group fails on centos 5.11

[pwaterz]

When trying to use the as function on centos 5.11 I consistent get this bash error

DEBUG [a0994eb0]    sh: -c: line 0: unexpected EOF while looking for matching `"'
DEBUG [a0994eb0]    sh: -c: line 1: syntax error: unexpected end of file

simple test

on roles(:whatever) do
   as(user: 'someuser', group: 'somegroup' ) do    
     execute :ls
   end
do

Command that is being ran

sudo -u someuser -- sh -c 'sg somegroup -c \"/usr/bin/env ls\"'

From what I can tell it's properly escaped. It works fine when only suppling the user and not a group.

There seems to be some escaping problem. If I remove the backslashes it works.

sudo -u someuser -- sh -c 'sg somegroup -c "/usr/bin/env ls"'
