qB 1.5.0 crashes when opening a .torrent file

[ToxAtec]

Hi,
I just compiled qbittorrent 1.5.0 (and libtorrent-rasterbar-0.14.5). I'm using slackware-current (not really "current", something between 12.2 and 13.0) and qt4-4.5.2.

The programm starts fine, but when I try to open any .torrent file, qbittorrent immediately crashes (disappears, not feezes) as soon as I have chosen a .torrent file and press "open".

Here is the backtrace:

bash-3.1$ qbittorrent
Warning: Local domain socket was not closed cleanly, deleting file...

Could you send me the torrent file at <email address hidden> ?
In the meantime, simply disable "torrent addition dialog" in program preferences.

[Christophe Dumez (hydr0g3n)]

This is what I thought, it has nothing to do with the torrent file. The torrents you sent me work just fine here. There must be something different on your system... Are you using 64 bits?

[Christophe Dumez (hydr0g3n)]

Would you be able to enable debug in qBittorrent (DEBUG=1 in src/src.pro) and recompile? then get a real backtrace in gdb?

I tried to figure out where the problem could occur but I could not. And since I cannot reproduce the problem, this is hard.

Hi !
First, please forgive my english.
My system is an Archlinux(up to date) and until today I run an older version of qBittorrent (I guess 1.4) without any problem.
Today I installed qBittorrent-1.5.0 from the Archlinux /community repository http://www.archlinux.org/packages/?repo=Community and surprise: the programm crashes and disappears from the screen when, as usual, it must appear the "Torrent addition dialog". What's going on? Thank you!

Hi,
I found out that the crash only occurs when the folder that would be displayed as the save path (/home/michael/qBT_dir for me) does NOT exist. Otherwise it just works as it should.

I also recompiled qBittorrent with DEBUG=1, but although the folder doesn't exist, qBittorrent doesn't crash :S

Thats what it says with DEBUG=1: http://pastebin.com/f123e1a91
It does not affect the debugging output if the folder does exist or not, BUT:
If it exists, the dialog window looks as usual, like that: http://img5.imagebanana.com/view/aw4yo041/qBT1.png
If it doesn't, there are strange symbols and numbers: http://img5.imagebanana.com/view/mh5o41w2/qBT2.png

I hope that helps.

By the way, I'm not using x64, I don't know what should be different otherwise. I'm having some dbus problems though.

[Christophe Dumez (hydr0g3n)]

Ok. I commited the fix on SVN. Thanks a lot for this critical bug report. I should release v1.5.1 soon.

[Christophe Dumez (hydr0g3n)]

v1.5.1 was just released.
