What is the expected behavior

Shouldn't close.

Steps to reproduce

Just open it up and wait.

Extra info(if any)

Worked fine a couple of hours ago.

Removing the package packagekit-qt5 seems to fix the issue.

did removing packagekit-qt5 fix your crashes?

did removing packagekit-qt5 fix your crashes?

I haven't try, but I don't think the fix should be removing packages.

zeromind · 2018-11-02T02:01:34Z

Same issue here, also on Arch Linux.
packagekit-qt5 is not installed.

still no clue?

zeule · 2018-11-09T07:15:38Z

Stacktraces are useless for debugging, happens only in Arch. Why don't you report that to the Arch bug tracker or build qt5-base with debugging enabled?

blackPantherOS · 2018-11-11T14:31:37Z

Stacktraces are useless for debugging, happens only in Arch.

Crashes on blackPanther OS as well...

@zeule No,thank you. Should I uninstall the qt5-base and install the qt-debug packages with debug symbols in order to get the backtrace without lost function name? (I'm a newbie for linux user and compiler.)

zeule · 2018-11-13T18:33:41Z

@zoggee I think you only need the qt5-base-debug package and whatever this package requires to install or replace.

Thank you very much!

of course. the highlighted line the important row

Thank you in advance!
@blackPantherOS Is it your own qbittorrent's PKGBUILD file? Could you post it completely?
I wanna learn how to compile according to the file?

@zeule When I type qbittorrent in comand line,I've got the warning message below:
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

Is it matter with the crash?
How Can I set the variable?

i'm getting this on Debian 10, a few seconds after starting.

i don't know what broke it. it worked earlier today, and i don't remember changing anything, nor adding any new torrents. i may have updated some packages, but i don't remember extensive updates, nor qt libs.

4.1.3 crashes the same as 4.1.7 from testing.

I think I have managed to correct this bug on my Debian 10 system by compiling (4.1.9.1) with a newer QT version (5.12.6). qBittorrent still reports version 5.11.3 which I can only guess is because of the environment.

Also: I was running qBittorrent 4.1.5 in Debian 9 (Qt 5.7.1). Upgrading to Debian 10 (the same version of qBittorrent with Qt 5.11.3) broke it and I got these segfaults whenever I tried to load the fastresume data (not with a clean data/qBittorrent folder). Don't know if it's relevant, but I also switched from XFCE to KDE in the process.

vlijmenfileer · 2019-12-19T16:54:37Z

I have the same. To be precise, the crash is triggered by going to the search tab, and then opening the Search plugins window.

Seeing how it started apparently randomly, and no critical packages had been updated or installed when it happened, I suspected the search plugins themselves, which I had recently updated.

After uninstalling all search plugins, qBittorrent does not crash any more, when opening the Search plugins window.
After installing a limited set from https://github.com/qbittorrent/search-plugins/wiki/Unofficial-search-plugins, qBittorrent does not crash any moreafter opening.
After uninstalling all plugins again and choosing "Check for updates" some random (default?, official?) set of plugins is installed, immediately after which qBittorrent crashes again.

My guess is the problem is in an update to one these random (default?, official?) plugins.

Qt: 5.11.3
Libtorrent: 1.1.11.0

Hi, I have the same issue.
I'm quite a very beginner on debian and linux and I'm not good at all in code, so I need a lot of explanations about how solving this issue... Thanks :)

qBittorrent version and Operating System
qBittorrent 4.1.5 & Debian KDE plasma 5.14.5

If on linux, libtorrent-rasterbar and Qt version
libtorrent-rasterbar9 & Qt 5.11.3

What is the problem
qBittorrent is closing by itself just after I opened it (less than 1 second after). It happened just after I tried to add a lot of trackers to one torrent.

What is the expected behavior(type here)
Not closing

Steps to reproduce
Adding a lot of trackers ?

Thanks to all for the reports. However, all crash reports here are from very old versions at this point. The root casue of these crashes has most likely been fixed in libtorrent/Qt/boost, etc.

Submit a new issue if you have any problems with 4.2.3, the latest version.

FranciscoPombal · 2020-04-08T15:24:25Z

Note: this problem seems to be related to Qt 5.11.3 and the usage of specific search plugins, or the tracker favicons in older Qt versions.

If you're on Windows or macOS, the most recent builds have been shipping with more recent versions for a long time now. On Linux, here are some possible workarounds, if you're stuck on that Qt version:
