Tracker is changed to one not in the list of trackers

[km_]

The active tracker for some of my torrents change automatically. This occurs only for torrents downloaded from one particular tracker, so it isn't necessarily a bug in Deluge but rather something I'd like to figure out why happens to be able to prevent it from happening.

• Upon starting the torrents, the correct tracker (the one listed in "Edit trackers") is shown in the "Details" tab for the particular torrent.
• Occasionally - for some torrents - Deluge changes to another tracker. In the current case (with screenshot) the active tracker changed from my passkey-included tracker URL to a public tracker "udp://tracker.publicbt.com:80". This tracker is not in the list of trackers when i click "Edit trackers". I've seen this happen for around 10 torrents the last few weeks.
• I have also seen that Deluge changes only the passkey from the tracker URL. This indicates that there is indeed a bug in the tracker and not Deluge, but I cannot understand why Deluge changes the tracker from the one listed in the torrent file anyway. The passkey tracker got me banned from the tracker a couple of days before my account was re-opened with a suggestion not to use Deluge. I'd love to continue using Deluge so I'd like to figure out how I can prevent Deluge from changing trackers on its own.

I have disabled "DHT", "LSD" and "Peer Exchange" in the network properties to no avail.

Any tips or suggestions?

Due to a severe bug all libtorrent extensions are enabled in 1.3.6, which includes tracker exchange which is similar to PEX. See: http://forum.deluge-torrent.org/viewtop ... =7&t=42299
