Crashes when folder select dialog is opened (Qt OS version and Qbit version differ) about qbittorrent HOT 15 CLOSED

Should be fixed by #20627
Any confirmation ?

from qbittorrent.

I can confirm the fix.

Had the issue on both Garuda, and KaOS. Did compile the git version, and the issue is gone. (Was triggered by the "Set location" feature.)

Thanks a lot

qBittorrent info:

Qt: 6.6.1
Libtorrent: 2.0.9.0
Boost: 1.83.0
OpenSSL: 3.2.1
zlib: 1.3.1

So what is the version of qBittorrent itself?

Qt version is 6.6.1 in one place and 6.6.2 in another one. Which of them is true?

Oh, sorry about that. qBittorrent version is 4.6.3. Regarding the Qt version, the qBittorrent > Help > About > Software shows 6.6.1.

But when I goto the Settings > About this System it shows 6.6.2.

EDIT: I ran qtdiag6 and it shows this:

Qt 6.6.2 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 13.2.1 20230801) on "wayland" 
OS: EndeavourOS [linux version 6.6.22-1-lts]

from qbittorrent.

In this case, the problem may be due to the fact that it is running with a different version of Qt.

@glassez How can I see where and why qBittorrent is using 6.6.1? In all the places I checked it shows 6.6.2, so how is qB able to find/load 6.6.1?

Thanks

Perhaps my previous comment was not clear.
Your qBittorrent was built using Qt 6.6.1, but run with Qt 6.6.2 (which is currently installed on your system).

Can't reproduce on Arch Linux, selection dialogs work me. So you definitely need to get the backtrace.

Although it's true that current qbittorrent 4.6.3-1 package was built with Qt 6.6.1 and qt-base was updated to 6.6.2 since. But minor Qt updates claim not to break compatibility and don't require rebuild.

Also wild guess: try another app where Qt file picker is used.

Also I have a feeling that it is somewhat connected to #20581

I followed your advice. I tried qdb and it did not show any errors when it crashed. I also tried X11 instead of Wayland, but still no difference. So then I downgraded all my qt6 packages to 6.6.1. Please refer to the screenshot below. Even with that it crashed. After that I tried other Qt apps. I tested in Haruna, Kid3, and qimgv. All of them I was able to view the file selection dialog. I'll have to keep hunting...

@glassez, #20596 has the backtrace.

What were the previous versions of KDE/Plasma and Qt?

Hmm .. I don't know exact version numbers but they were not 6, they were 5.

I was finally able to put a few problems together.
Now I can reproduce it. But since (fortunately) it has the same roots as other related problem that have already been fixed, it is also fixed along with them at the same time.
