Deluge container crashes when checking torrent with special characters

LSIO Discussion Container Support

Deluge docker arm64 crashes when checking torrents files that contain specific (in my case) portuguese characters such as Á, Ò, Ê, Ç, Õ. At least that’s what I think it’s happening.

The steps I take are:
1-Add torrent in Paused State do Deluge
2-Set the files folder for said torrent
3-Force Recheck torrent
4-Container crashes with this error output:

I’ve tried this same steps with the same torrent with special characters in a native linux install (Deluge 2.0.3, libtorrent 1.2.9.0) and it didn’t reproduce the error there, everything went smoothly.

Anything I can do to keep using Deluge with this kind of torrents?

Anyone knows if this can be worked on?

Does the issue present when using the application outside of docker? ie, is this a container issue or an application issue.

disregard i clearly can’t read.

You should open a github issue and we can take a look at it. I wouldn’t expect anything fast, you’re the only user to ever report this and the error isn’t super helpful in narrowing down the cause. It looks like something should be latin1 rather than utf8… but …

actually it looks like this has been an ongoing issue without resolution for a while…

i also just noticed that you’re comparing the most updated deluge to a version that is old (Deluge 2.0.3, libtorrent 1.2.9.0) , if that version works as expected you should use the tag that gives you that version until deluge fixes the issue

The Deluge app inside the container crashes until the files are erased from disk and the container restarted.

Since I made the test and the native Deluge app worked, I thought this was an issue with how the container was built. Maybe missing some dependency to deal with different characters.

The torrent that gave this problem is long gone.
Now trying other torrents on Deluge with similar special characters and it seems to work fine. Maybe it was just that one torrent and it had some different characters.
