Crashes when adding new Trackers

[dagaz]

Hello!

This is my first bug report here.

I am using the qbittorrent v3.0.0 with Ubuntu 12.04

"uname -a" gives out:

Linux ubuntu 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

When i right-klick into the tracker fied and select "Add new Tracker" and add these trackers:

udp://tracker.openbittorrent.com:80
udp://tracker.publicbt.com:80
udp://tracker.istole.it:6969
udp://tracker.ccc.de:80

and press OK then qbittorrent crashes.

I started qbittorrent in a terminal. The output is (i replaced ma username with "USER"):

USER@ubuntu:~$ qbittorrent
Couldn't set environment variable...
"sni-qt/10367" WARN 21:21:33.894 void StatusNotifierItemFactory::connectToSnw() Invalid interface to SNW_SERVICE

Does this happen only for magnet torrents? I fixed a tracker addition crash in v3.0.1 that would occurs for torrents that don't have metadata yet (magnet torrents in initial stage).

[cdumez]

Cannot reproduce in v3.0.1 so I assume this was the bug I was talking about. Closing.

Till now it only happens with torrents with magnet-links. With torrents from files i cannot reproduce it.
Also I recognised that the trackers which are includet in the magnetlink are not displayed at first. Only DHT, PeX and LSD. after some time the torrent starts, i assume though DHT, PeX or LSD and then sudenly there is a tracker and later there are more trackers. Also sometimes nothing happens with the torrent for hours (its active and not in cue). Then I tried to add the trackers and the result is the crash.

OOPS, saw to late that the issue is already closed.
