Does it fail on any other websites too? For example https://imgur.com/upload

Yeah it doesn't fail. After a little bit of testing, I discover that:

- If the website requests "Custom Files" in the field File Type, it will not fail
- If the website requests "Custom Files" and I switch to "All Files", it will fail

- If the website requests "All Files", it will fail.
- If the website request "All Files" and I enter the file type in the second field, for example pdf, jpg etc, it will not fail

I guess in short, "All Files" is the issue for some reasons.

I also discover that if this issue with "All Files" happens if the folder has too many files. Otherwise with some other folder with less files, even with All Files, it won't fail.

Thanks! Can you reproduce the same thing with "Open" dialogs that are not using the xdg-desktop-portal? E.g. any KDE app installed using native packaging, rather than Flatpak or Snap.

Yes, KWrite and Kate also demonstrate the same behavior.

Here is the log from KWrite on Wayland (All Files)

[my2ndangelic@m2a-acer ~]$ kwrite
libkate.time: All plugins loaded in 0 ms
libkate.time: Created KateMainWindow in 46 ms

--- I open file and start scrolling down, then the dialog closes and it spit out. ---
kf.kio.core.connection: Socket not connected QLocalSocket::PeerClosedError
kf.kio.core: An error occurred during write. The worker terminates now.

QThreadStorage: entry 1 destroyed before end of thread 0x55a448377360
--- End of whatever here ---

However, those last 7 lines will always spit out if I scroll and cursor is on the file name. Sometimes the File select dialog will not close if the folder doesn't have too many files but terminal also spits out those last 7 lines.

I have recently updated to the new kernel and framework. Just want to report that it hasn't been fixed. Forgot to change the status last time I comment.

Possibly fixed by https://invent.kde.org/frameworks/kio/-/commit/6552bc6f280b2eddff4b1da931004a8a9230ac81.

Can you test again with any of the following:
1. https://invent.kde.org/frameworks/kio/-/commit/6552bc6f280b2eddff4b1da931004a8a9230ac81 manually built on top of your frameworks-kio package
2. git master of frameworks-kio
3. Frameworks 6.16 once it's released in a few weeks

Hi again. I have upgraded to framework 6.16. This time, the file dialog will still crash.

For Chrome
- However, instead of closing, it will automatically open a new one.
- The dark screen effect will disappear, the screen effect brighten again for the window inside)
- The log:

For KWrite (because Kate doesn't output anything to the Terminal)
- It just close and does not spawn a new one. This time, it applies both to the Open and Save dialogs. Note that this problem only applies if your file type is "All Files"
- If you visit the first folder and it crashed, it doesn't output any log, just close
- After crashing the first time, it will start spamming the terminal with logs
- The log:
[my2ndangelic@m2a-acer ~]$ kwrite
libkate.time: All plugins loaded in 0 ms
libkate.time: Created KateMainWindow in 45 ms

--- After the crash, I open the "Open" dialog and scroll around until it crashed. ---

That sounds like a different behavior entirely. Let's get a new bug report for it, since it will likely have a different root cause and need to be investigated separately.
