Deluge crash with 'exceptions.UnicodeDecodeError' if python-rencode is installed

[Andrei Borzenkov]

I run Ubuntu with Russian locale and all desktop directories have Russian name by default (Downloads, Video, etc) so deluge by default saves torrents in directories with non-ASCII paths. Today I tried to install deluge 2.0 from ppa and it crashed when I tried run it. I then reverted to version shipped with Xenial which still crashed. I removed additional packages pulled in by 2.0 one by one and to my surprise mere existence of python-rencode causes deluge crash. This is rather show stopper for me as I cannot update to 2.0 (which I need due to improved proxy settings).

We ship a python-only version of rencode with Deluge so the rencode cython version must have an issue.

You might be able to force remove python-rencode using dpkg after installing Deluge 2.0, hopefully making it usable again...

This will need reporting upstream to: https://github.com/aresch/rencode

I have opened an issue, but given that upstream is already at 1.0.5 I do not hold my breath ...

It still fails using the most recent packages.
