I've already tried to de-install qBitorrent and reboot then reinstall it but it still crashes at start,
what can I do to correct this ?

Thanks by advance :)

Steps to reproduce

v4.5.2-3 was working till I tried qBitorrent v4.6.6.-7 from https://download.opensuse.org/repositories/home:/tangerine:/deb12-xfce4.18/Debian_12/

Additional context

No response

Log(s) & preferences file(s)

seems that the configuration has been replaced by an almost empty one :(

[BitTorrent] Session\QueueingSystemEnabled=false

here is a log (when config was there)

qBittorrent : v4.5.2

Sigh, yet another debian "stable" user to report a bug in a 2+ year old version.
5.1.0 is the current latest.

Hello folks :)

seems you don't like this one ;) : the problem was that the installation of that 'newer' v4.6.6-7 version somewhat killed (dunno why it was dimmed as non needed btw,) the 'xcb v2.4.8 app, that sole missing stuff was making it to crash at start.

after being reinstalled it works fine again :)

btw II 5.1.0 isn't available yet to debian 12.11 stable ;)

btw III there are still a thing that's bugging me there, when I first installed qBittorrent in place of ktorrent (when I switched from Mageia to debian 10) I've seen no differences in download speed (still fully using the 10GB/s ftth speed (was getting things at 105-115 MO/s), but after some updates and now with Debian 12 I see a slight cut in download speed, that's down to 1-1.5 MO/s ...)
did you change something that could explain this ?

I ask, 'cause if I download with curl or else I still go full 10 Gb/s speed max but not anymore with qBittorrent :(

btw IV thanks anyway for your good software ^^)
