When I click Trackers or the Peers tab on certain torrents qbittorrent crashes. This usually happens on torrents from Swedish sites.

Here is the terminal output when running qBittorrent normally:
Catching SIGSEGV, please report a bug at http://bug.qbittorrent.org

Same as issue #222?

Question: Does the same torrent crash the app, or sometimes it works fine? If it always crashes the app could you post a link to such a torrent?

Yes, #222 is the same issue. So I will close this (I have provided a solution in the comments on that page).
