Doesn't seem to happen with Qt 5.

  1. Go to Edit Trackers

Right click/context menu

empty clipboard crash

Also crashes with add trackers under trackers tab:

I wonder, is this a bug on all platforms or just windows

All (tested in linux) since it looks like a Qt bug.

it looks like a Qt bug.

Maybe, or it's a change in Qt's behavior/handling of mime data.....

  • This issue only appears with Qt 6.4.0/6.4.1 & 6.5.0 Beta 1 (Qt <= 6.3.2 unaffected)

Also crashes in peers tab.

Should this be reported to Qt instead of here?

Steps to reproduce

2. Go to Edit Trackers (i think other input boxes have this issue)
3. Paste but there is nothing in your clipboard
4. Crash!

Also crashes on my end.

I have a similar(?) issue, that happens less frequently:

32# RtlUserThreadStart in ntdll

Context:
The client was minimized in the system tray.
I have a PowerShell script that run after torrents finishes download (PowerShell actually opens)

When/how it happens:

  1. The download finishes
  2. The PowerShell script runs fine
  3. At the same time, the qBittorrent client crashes.

Keep in mind that this issue doesn't happen super often. I had a similar issue with the qt5 version, except it was a lot more frequent.

I think it would be better if you open up a new issue about that

UPDATE: reported the bug to Qt here and the developers acknowledged it as critical and are currently working on a fix.

Should i close this issue or is it preferable to keep it up until the issue has been fixed by Qt? @xavier2k6

@Damaj301damaj-lol Will leave it open for now, also you should've probably had pasted or at least linked the stack traces from #18317 (comment) & mentioned the regression from #18317 (comment) in your Qt Bug Report to have aided in narrowing down the issue for Qt Dev's as your link to this ticket is broken over there.

I can confirm that the fix from QTBUG-110070 which is included in Qt 6.4.3 & Qt 6.5.0 resolves the reported issue for this ticket.
