  1. have a non-paused torrent (may be inactive)
  2. try to right-click and Set Location

Are you really able to reproduce this problem by repeating these steps?
Does it affect any torrent or any special ones?

It happened both times I tried to move files, but I did some tests and it seem that the crash happens when I move files from inside folder with japanese name somewhere else (it didn't happen when I tried to move files inside it never mind it seems to be random, but it's very easy to reproduce by moving in and out of the folder with japanese name)

it might be irrelevant, but my system locale is US English with UTF-8 support
system locale

I also experience this crash. In my case I am moving Japanese torrent into non-Japanese path. Crash doesn't happen every time, but often enough to be easy to reproduce.

As a side-note, I use English system locale and UTF-8 is disabled.

@eggpa Do you have any stack trace? What operating system?

10.0.22000

@13xforever Isn't that build version Windows 11 & not 10??

@glassez this may explain the short stacktrace (If Windows 11 SDK wasn't included at release/compile time?!)

Yes, it's Windows 11, I just copied from the crash info as is

@xavier2k6, I do have stack trace, didn't post it because few top lines are the same so I thought it's not necessary, but here it is. I am using Windows 11 Pro N x64, version 21H2, build 22000.318, although in qBittorrent crash info it says Windows 10.

A few lines at the top have little use for us. They are always the same, since they relate to the logic of generating the stack trace itself.
I can't see the explicit relation of your Crash (based on the provided stack trace) with file operations, encodings, locale, etc. It seems to be happening somewhere in the Qt logic for Menu processing. Moreover, it seems to me that I have already noticed similar stack traces.
Can anyone affected try to test v4.4.0rc1 build based on Qt 5.12 instead of 6.2?

I was not able to reproduce this problem on Qt 5.12.

As I was playing with Qt 6.2 I managed to get two more stack traces which are slightly different:

Additionally, I believe I found a way to reproduce this problem with a very high probability (was able to do it 10+ times in a row):

  1. right click on any torrent
  2. right click on "Set location..." and hold for about 2 seconds
  3. release right mouse button
  4. click "Cancel" in the newly opened file explorer
  5. crash should occur

Additionally, I noticed that sometimes qBittorrent crashes so badly that it doesn't even show the crash info :(

@eggpa Thank you!, can confirm that reproducible steps below result in a crash (Windows 10):

  1. right click on any torrent (doesn't matter if paused or active)
  2. right click on "Set location..." and hold for about 2 seconds
  3. release right mouse button
  4. click "Cancel" in the newly opened file explorer
  5. crash should occur

I can't reproduce it with official qBittorrent 4.3.9 or with v4.4.0rc1 (Qt5 version) which both use Qt5.15.2

@glassez BTW, I don't think this will be an issue in whatever official qBittorrent version will use Qt6 since set location is integrated into torrent options in master.......however it may pop up somewhere else & will require different repro steps.

Just checked with the latest master commit & Qt 6.2.2 since the set location option is back in the context menu using the repro steps & profile mode - observe crash, but now with slightly different stack trace.
