I think we need to escape the \. So basically instead of \ use \\

/home/nero/repos/aptly/python-aptly/aptly/publisher/__init__.py:179: SyntaxWarning: invalid escape sequence '\}'
  nodes_raw = re.findall('[ \t]+"([^"]+)".*label="{(Repo|Snapshot|Published) ([^|]+)[^\}"]+}"', dot_data)
/home/nero/repos/aptly/python-aptly/aptly/publisher/__init__.py:591: SyntaxWarning: invalid escape sequence '\ '
  parsed = re.match('(.*)\ (.*)\ (.*)\ (.*)', ref)
