Confirm normal use of bzr

As bug 1175462 has been living a life of its own for nearly two years (and I am not criticizing here), I need a confirmation:

Is the reproduction scenario below a reasonable usage of bzr (and thus, one has to wait for the bug to be fixed or propose a patch) or is it simply a wrong assumption about the way one is intended to use Bazaar ?

Reproduction scenario:
 * step 1: create a folder (mkdir foobar)
 * step 2: add folder to bzr revision control (bzr add foobar)
 * step 3: shelve it _before_ committing it (bzr shelve -m "current-task" foobar)

Thanks
