kf.service.services: KApplicationTrader: mimeType "x-scheme-handler/file" not found I always get this message when some application open by mine type. How can I add this mime type to somewhere? Is there a registry for this?
Maybe we're seeing the same thing? https://bugs.kde.org/show_bug.cgi?id=443319
Can confirm this on kf5 5.86.0. Hope following snippet is helpful. Before, below code would open the example.js file in text editor. Now it fails with: ``` kf.service.services: KApplicationTrader: mimeType "x-scheme-handler/file" not found Could not launch external editor. ``` ``` const QUrl script = QUrl::fromLocalFile("..../scripts/example.js"); KIO::OpenUrlJob *job = new KIO::OpenUrlJob(script); job->setUiDelegate(new KIO::JobUiDelegate(KJobUiDelegate::AutoHandlingEnabled, app()->mainWindow())); if(!job->exec()) { qDebug() << job->errorString(); if(!QDesktopServices::openUrl(script)) qDebug() << "Could not launch external editor."; } ```

Looks like it's fixed in 5.87.0
Present with 5.87 for me.
This bug can be triggered by both "xdg-open" and "kde-open5". I think I just find the related code is here: It bypasses "x-scheme-handler" but didn't bypass "x-scheme-handler/file", https://invent.kde.org/frameworks/kservice/-/blob/v5.89.0/src/services/kapplicationtrader.cpp#L26
The last comment is wrong, but I cannot edit it. The code was submitted here. https://phabricator.kde.org/D25698
I'm encountering this issue on kf5 5.90.0: $ xdg-open . kf.service.services: KApplicationTrader: mimeType "x-scheme-handler/file" not found KDE Plasma Version: 5.23.5 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.2 Graphics Platform: Wayland
I'm encountering this on an up-to-date Arch Linux system. Plasma Desktop: 5.24.2 KDE Frameworks: 5.91.0 Qt: 5.15.2 Platform: X11 Hardware: Nvidia The bug can be reproduced consistently on my multi-monitor setup: 1. Open "Display Configuration" in System Settings 2. Disable primary monitor 3. Enable primary monitor after some time The above steps are sufficient to reproduce the problem. Restarting kwin/plasmadesktop does not help. The problem does not occur on a fresh restart though. The monitor needs to be disabled to reproduce it. Examining with Journalctl, I see : kwin_x11[2736]: qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 16715, resource id: 138412039, major code: 18 (ChangeProperty), minor code: 0 kf.service.services: KApplicationTrader: mimeType "x-scheme-handler/file" not found kioclient5[196052]: kf.service.services: KApplicationTrader: mimeType "x-scheme-handler/file" not found kwin_x11[2736]: qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 8651, resource id: 142606341, major code: 18 (ChangeProperty), minor code: 0 kwin_x11[2736]: qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 8656, resource id: 142606342, major code: 18 (ChangeProperty), minor code: 0 kwin_x11[2736]: qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 8660, resource id: 142606343, major code: 18 (ChangeProperty), minor code: 0
a workaround has been found - you need to: enable hidden files in dolphin then go to your home dir (/home/username) then go to hidden .config dir in there you need to find file named mimeapps.list edit it, add this string (x-scheme-handler/file=org.kde.dolphin.desktop;) to all sub strings for example: [Added Associations] ..... ..... x-scheme-handler/file=org.kde.dolphin.desktop; [Default Applications] ..... ..... x-scheme-handler/file=org.kde.dolphin.desktop; then execute this command in the terminal: update-mime-database ~/.local/share/mime it's worked for me, after that system links has became open in dolphin more info: https://wiki.archlinux.org/title/XDG_MIME_Applications https://bugzilla.redhat.com/show_bug.cgi?id=674321
(In reply to pridoorok from comment #10) > a workaround has been found - you need to: Wow! That worked perfectly! Thank you so much. :) I wonder why this is even needed for KDE? Why doesn't it "just work" as expected by default?

I'm on Wayland, Frameworks 5.91, Plasma 5.24.4, Fedora 35.

Git commit a4c404603bbf43fda2d60c82c814527bde0a8352 by Ahmad Samir. Committed on 19/08/2022 at 14:31. Pushed by ahmadsamir into branch 'master'. DesktopExecParser: don't kioexec if there is a handler for scheme This fixes an issue where the code called KApplicationTrader::queryByMimeType("x-scheme-handler/file"), which would trigger a warning in KApplicationTrader, because there is no x-scheme-handler/file mimtype.
