Created attachment 154635 [details] Screenshot of the error message SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Open dolphin 2. Drag a file to somewhere else, click "Copy Here" OBSERVED RESULT Doesn't copy the file, instead a red popup saying "The file or folder Message recipient disconnected from message bus without replying does not exist." Sometimes dolphin freezes for some time (and other programs too for a short time) EXPECTED RESULT The file copies to the desired location fine, and dolphin doesn't freeze.

Still reproducible on 23.04.2
(In reply to kocelfc from comment #1) > Still reproducible on 23.04.2 So, I am running Gentoo and noticed that 22.12.3 was still in the tree, and built that, and the problem wasn't there. Then I decided to do a bisect between 23.04.2 and 22.12.3 which led to nothing. Then I started checking for failing services, and noticed that xdg-document-portal.service was failing because I hadn't had the fuse module enabled in my kernel.

After building the kernel with CONFIG_FUSE_FS=m, dolphin started working properly on all versions. I am going to attach logs from dolphin with both 22.12.3 and 23.04.2 with and without fuse.

Happens in Arch Linux as well, using 23.04.3
I saw this on gentoo after upgrading from 22.12.3 to 23.04.2. Loading the fuse module does indeed seem to fix it. It seems this is required now, but I can't really see a reason why. In the past, I only would load fuse when I need to use appimages. I don't use snaps, flatpacks, etc.
Happens on Arch Linux with fuse module loaded.
So far, on Arch Linux, this only happens to a dolphin process started for a different user, using kdesu dbus-launch: kdesu -u user dbus-launch dolphin
