Comment 5 for bug 740005

@lamskoy: This is not the correct way to fix this. Here is why I think so:
1. This should be in advanced preferences not in regular ones.
2. Why only the tracker extension? users will wonder why they can disable the lt_tracker extension but not the other ones (qBittorrent supports a few others). Thus, a simple checkbox does not do the trick.
3. From a programming point of view, your patch is fine although I don't think it should be called LT (since LT means LibTorrent and the extension is called lt_trackers).

I will file a bug report against libtorrent itself. I believe the the best fix there is to disable this extension ONLY for private torrents. Similarly, DHT is already disabled for such torrents.
