Description Alexey Shildyakov 2011-05-29 11:29:41 UTC
Application: ktorrent (4.2dev)
KDE Platform Version: 4.6.3 (4.6.3) (Compiled from sources)
Qt Version: 4.7.3
Operating System: Linux 2.6.38-gentoo-r3 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
1. I opened Trackers view.
2. Then I'was opening the torrents for the same file (the same torrent but different torrent-files). KTorrent was showing me "Trackers are added" to the torrent. But I don't see any changes - only one tracker presented in Trackers list for the torrent. Do it several times for different torrent-files.
3. I tried to add some trackers manually. Add 2 trackers in Add trackers window, click OK.
4. KTorrent show me window like "This trackers have already presented in trackers list" 5. After I clicked OK, KTorrent crashed.
