That seems to be a bzip2 feature/bug.  (It behaves the same on RedHat 7.1.)

$ bzip2 --version
bzip2, a block-sorting file compressor.  Version 1.0.1, 23-June-2000.

bzip2: I won't write compressed data to a terminal.
bzip2: For help, type: `bzip2 --help'.
-------------------->8--------------------

As you can see, the --version flag doesn't stop bzip2 from trying to 
compress standard input.
Possible workarounds:

$bzip2 --version --help 2>qqq

$bzip2 --version </dev/null >/dev/null 2>qqq

     I always wondered about the meaning of life.   So I looked it
     up in the dictionary under "L" and there it was - the meaning
     of life.  It was not what I expected.                  - Dogbert
