Deluge crashes if python-rencode is installed

[arvidjaar]

I found that on Ubuntu 16.04 Deluge would crash trying to access non-UNICODE file names if python-rencode package is installed. More details are in this bug report: https://bugs.launchpad.net/bugs/1705066 (a bit long so not duplicated here).

The version in Ubuntu 16.04: python-rencode 1.0.3.

Please let me know what additional information is required. Thank you.

Have you tried uninstalling python-rencode and re-running the command? It looks like the error is actually occurring within Deluge and not rencode. It looks like it's failing on decode, which is a bit strange because the string should already be a unicode object since rencode.loads() is being called with utf8_decode=True.

@aresch

Have you tried uninstalling python-rencode and re-running the command?

Yes, of course. That is how I found that this package mysteriously breaks deluge.

It looks like the error is actually occurring within Deluge and not rencode.

I opened bug against deluge and was advised to report problem here. Specifically as comment on this bug report puts it "We ship a python-only version of rencode with Deluge" so it appears installed version takes precedence. I am open to try whatever steps you recommend to better diagnose it, but I am neither deluge nor recode nor python in general expert so I need guidance.

The fact currently is - just be installing this package deluge stops working. I am not interested in finger pointing, all that I want is fixing this problem, be it in deluge or in recode; and to do it I need your (both) assistance.

Would it be possible to show me the output when you don't have python-rencode installed? All I would need is the torrent status directly after where it crashes with python-rencode. I'd like to see what strings it's trying to decode.

Sure.

Could you run: deluge-console -L DEBUG info 521ef3ac4e7e62db15f73e8c0e3db68c7ff5a216 for both python-rencode and without?

[arvidjaar]

Sure
