fix: replace except: with except Exception: (by haosenwang1018@github) Remove bare 'except:' statements replace with 'except Exception'. In roundup_xmlrpc_server.py I changed Exception to BaseException so the database gets closed on signals as well. The rest of the changes do not look like they affect data integrity and are commited as supplied.
