Although the "--exclude" functionality should be implemented in Python tar support and it's not strictly a bazaar bug, current situation after one year is that "bzr export" stills creates a package with all the files and i think it's pretty common when you create a tar file to exclude some files from the repository.
Work-around (exporting to /tmp, and creating a tar file), is just that, a work-around.
