  11 > Retitled this bug report since it seems to be specific to Python 3.

  13 > The `rst` plugin is probably more commonly used with Python 2.
  14 > It seems likely that there is some Python-3-specific bug in `proxy.py`,

  25 looks like the problem is in proxy.py
  26 ml = _IkiWikiExtPluginXMLRPCHandler._read(in_fd).decode('utf8')
  27
  28 without decode('utf8') is working
  29
  30 > That call was introduced
  31 > [[to fix a bug under Python 2|bugs/crashes_in_the_python_proxy_even_if_disabled]]
  32 > so it cannot just be removed, but I've put a proposed branch on

  35 tested and fixed with patch [http://git.pseudorandom.co.uk/smcv/ikiwiki.git/commitdiff/38bd51bc1bab0cabd97dfe3cb598220a2c02550a](http://git.pseudorandom.co.uk/smcv/ikiwiki.git/commitdiff/38bd51bc1bab0cabd97dfe3cb598220a2c02550a) and patch [http://git.pseudorandom.co.uk/smcv/ikiwiki.git/commitdiff/81506fae8a6d5360f6d830b0e07190e60a7efd1c](http://git.pseudorandom.co.uk/smcv/ikiwiki.git/commitdiff/81506fae8a6d5360f6d830b0e07190e60a7efd1c)
