New submission from Fabio Erculiani <lx...@sabayonlinux.org>:
TarFile.makelink() is plain broken.
Test file:
http://git.sabayon.org/entropy.git/tree/libraries/tests/packages/amarok-2.2.2.90.tbz2
_extract_member calls makelink which does os.symlink() and then falls to the
else branch and calls back _extract_member(), which calls makelink() which
calls os.symlink() and causes errno 17.
