It's been happening for 2 versions now, torrents form a private tracker that I use cause Tixati to crash, this also happens even if I use the hash. The tracker is Russian so I wonder if it's because of the Cyrillic unicode or something.
Is there a contact where I can send some .torrent files to the devs for checking?

Upload the torrent files somewhere and post a link here. Or post the magnet link here. Be sure to post the tracker as well since it may be part of the problem. They will be sent to the Devs and not posted publicly. Make sure you are sending the crash reports in.

why do you not allow posting torrent links in forum?

Thanks ZarkBit for all the information. The Dev is working on this and it should be fixed in the next release.
