qbittorrent 4.5.0 won't exit

[karabaja4]

qBittorrent & operating system versions

qbittorrent: 4.5.0 x64
Operating system: Arch Linux x64
Qt: 6.4.1
libtorrent-rasterbar: 2.0.8.0

What is the problem?

Clicking right-click -> Exit in the tray icon does not close the qbittorrent proccess. Instead, it becomes unresponsive (left-click does not restore the window aynmore). killall qbittorrent is required to exit.

Steps to reproduce

1. Right click the tray icon.
2. Click Exit.
3. The tray icon remains and the process becomes unresponsive.

Additional context

4.4.5 took around ~10 seconds to exit after clicking "Exit", but it did eventually exit.
4.5.0 just stalls.

Same here!

It only exit when I type: 'killall qbittorrent' twice in a row..

Out of curiosity can you also test with official AppImage (download on mainstite)?

[karabaja4]

Same deal with the AppImage, it just spams stderr with this error output until it is killed with 2xSIGINT.

Arch Linux
Same problem

What happens if you disable the tray icon? Preferences->Behavior->Show qbittorrent in notification area

[Rootdiv]

I have the same problem, and at the same time there is only an Exit button in the menu. If you go to Settings-> Behavior-> Show qbittorrent in the notification area and disable the display of the tray icon and click apply, then enable it and click apply, then everything works as before the update.
Ubuntu Mate 22.04.1 gtk2

[sledgehammer999]

I see that most of you are on Arch and probably a bit knowledgeable: Can you try compiling 4.4.5 using the same dependencies as 4.5.0 (especially the Qt version) and report if the problem happens there too?

[karabaja4]

Nothing has changed in regards to Qt version inside the Arch package between 4.4.5 and 4.5.0, and I'm positive that I updated only qbittorrent when doing the update and when this bug started to happen.

[sledgehammer999]

Which DE are you using?
I have tried clean VMs of Ubuntu 22.10 (gnome), Xubuntu 22.10 (xfce) and Arch (KDE).
I can't reproduce it. The tray menu works correctly with the PPA version(ubuntu), the distro version(Arch) and the AppImage on the above VMs.

EDIT: I also don't get crashes on exit.

I'm using Ubuntu Mate 22.04, qbittorrent installed from PPA

[karabaja4]

I'm using Openbox and tint2 on X11 on Arch.

What does the following return?

BTW, this seems like a duplicate: #18093

[rial1106]

Same on Artix Linux.

Qt: 6.4.1
Libtorrent: 2.0.8.0
Boost: 1.80.0

OpenSSL: 3.0.7
zlib: 1.2.13

I also require 2 killalls to kill the program.

Edit (Added Error Log from ~/.xsession-errors)
log.txt

I've tried to remove all duplicate lines of the log and this is what i got using

I don't use a Desktop Environment. I use XMonad as my window manager and startx. When I try to close qbittorrent the icon does remain in my tray and when I press it, it doesn't do anything. I use trayer as my tray program.

[Rootdiv]

In the update dated November 30, 2022, the problem persists.
Ubuntu Mate 22.04.1 gtk2

[marillat]

@Rootdiv even if notification is disabled ?

[sledgehammer999]

Is anyone able to do their own compilations? If so, can you try with this patch? patch->#18108

[Rootdiv]

@Rootdiv even if notification is disabled ?

No, the problem is observed only when starting qbittorrent and until the tray notification is turned off and on

[Rootdiv]

In the update dated December 1, 2022, the problem persists.

@Rootdiv Which package version ?

Should be fixed.

Should be fixed.

But the behavior is the same as I described here #18072 (comment)

What behavior do you talk about? Note, this Issue is about "qbittorrent 4.5.0 won't exit". If you have another problem please discuss it in appropriate Issue.

If you do not perform the above actions, then everything corresponds.

[karabaja4]

This is fixed for me with the qbittorrent from the git master branch.

[msagebiel]

I have the exit problem on windows 10 and there are several threads. I kind of solved it by going back to openvpn . wireguard interface binding didn't exit qbittorrent and binding left on localhost and vpn ip...process can't be killed, stays days. Ubun WG no issues.

[karabaja4]

I am closing this issue since the root cause was fixed and further discussion seems to bring this out of focus. Please open new tickets for other issues.
