Package: qbittorrent-nox
Version: 4.2.5-0.1
Severity: important

Dear Maintainer,


* What led up to the situation?

Ran aptitude safe-upgrade this morning which updated qt5 libraries. After reboot, qbittorrent-nox web UI is inaccessible.
Tried opening web UI in Chrome and Firefox and both browsers download the page instead of opening it. Backend works just
fine as radarr and sonarr are both communicating with it just fine but web UI is broken.

* What exactly did you do (or not do) that was effective (or
ineffective)?

Restarted qbittorrent-nox several times.

* What was the outcome of this action?

qbittorrent-nox backend works, web UI does not.

* What outcome did you expect instead?

Expected web UI to work as designed.

Hello,
I've experienced this bug today in debian bullseye (11.0).

Hello,
I've set the severity of serious because this bug is making qbittorrent-nox unusable (you cannot enter Web UI and therefore you have no way to control the program). I'm also worried that this bug might slip into the release.

Regards

I've tested that with those environment but couldn't reproduce it,
Web UI works fine.

- sid
- bullseye on docker
- fresh install bullseye on KVM

So, once tags it as unreproducible and downgrade severity.


Could you install qbittorrent-dbg and run it with strace as
"strace qbittorrent-nox --skipdialog=true" and send debug log,
please?

Hello,
I think the issue for me is, that with libqt5core5a 5.15.2+dfsg-5 the qbittorrent-nox reports this content type:

content-type: text/html

while with version 5.15.2+dfsg-7 it reports the following content type:

content-type: application/x-extension-html

and firefox instead of displaying the web page, it offers to download it.

Hello,
was searching more and seems like the following bug (which is resolved) is fixing the issue:


I've tried the deb file attached to comment 37 and it fixes the issue.

control: reassign -1 libqt5core5a
control: affects -1 qbittorrent-nox
control: tags -1 -unreproducible
control: block -1 by 989744
Okay, it's libqt5core5a's issue, thus reassign to it.
