Revert "try to remove other bugs", commit57266085b9. Revert "try to fix previous", commit8e40377068. Revert "attempt to fix more warnings!", commit66b6933a38. I put by mistake on the MR due to some automatic scripts. Their state are pretty experimental. Signed-off-by: Frediano Ziglio <fziglio@redhat.com>
