When I update .bashrc and execute "source .bashrc" , error happen like this.

-----------------------------------------------------------------------------------------------
$ source .bashrc
-sh: /etc/bash_completion: line 273: syntax error near unexpected token `<'
-sh: /etc/bash_completion: line 273: `  done < <( compgen -d -- "$(quote_readline "$cur")" )'
-----------------------------------------------------------------------------------------------

This is a bug described in debian bug # 502804.

This bug fixed in bash-completion_1.0-1 , but when I execute
