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. Drag file to folder 2. Cursor menu should display "Move, copy, link" but only shows "Copy,link" 3. Drop file with "Copy" OBSERVED RESULT Message box or error bar in panel: "The file or folder Message recipient disconnected from message bus without replying does not exist." EXPECTED RESULT Copy file SOFTWARE/OS VERSIONS Windows: n/a macOS: n/a Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: 5.108.0 Qt Version: 5.15.10 ADDITIONAL INFORMATION This bus was reported in neon, but hasn't been acted on https://bugs.kde.org/show_bug.cgi?id=472591 Dolphin is now essentially useless. It's a fairly major that a user can get it into this state. No error messages are issued in dmesg, /var/log/messages or on the command line output of the program.
This appears to be a bad interaction between KDE and dbus that cripples dolphin. CLI and pcmanfm-qt can both copy files no problem. Even the desktop (managed by plasmashell) can copy files without errors. But dolphin and konqueror are completely blocked. The outpur from dbus-monitor is large but shows a lot of errors like: signal time=1692908521.092194 sender=org.freedesktop.DBus -> destination=:1.264 serial=2 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameAcquired string ":1.264" signal time=1692908521.092263 sender=org.freedesktop.DBus -> destination=:1.264 serial=4 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameLost string ":1.264" method call time=1692908592.896673 sender=:1.247 -> destination=org.freedesktop.DBus serial=120 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=GetNameOwner string "org.freedesktop.portal.Documents" error time=1692908592.896710 sender=org.freedesktop.DBus -> destination=:1.247 error_name=org.freedesktop.DBus.Error.NameHasNoOwner reply_serial=120 string "Could not get owner of name 'org.freedesktop.portal.Documents': no such name" method call time=1692908592.897904 sender=:1.247 -> destination=org.freedesktop.portal.Documents serial=121 path=/org/freedesktop/portal/documents; interface=org.freedesktop.portal.FileTransfer; member=StartTransfer array [ dict entry( string "autostop" variant boolean false ) ]
This issue is caused by CONFIG_FUSE_FS=m compiled into the kernel. Changing the config to CONFIG_FUSE_FS=y is a workaround but doesn't fix the issue. Why should kde require static fuse filesystem to be able to transfer files? Anyway please mark this bug as WORKAROUND This doesn't work: vanaert jesnow # zgrep -i fuse /proc/config.gz CONFIG_FUSE_FS=m CONFIG_FUSE_DAX=y this works: vanaert jesnow # zgrep -i fuse /proc/config.gz CONFIG_FUSE_FS=y CONFIG_FUSE_DAX=y
$ zgrep -i fuse /proc/config.gz CONFIG_FUSE_FS=y CONFIG_FUSE_DAX=y Still fails. The file or folder Message recipient disconnected from message bus without replying does not exist.

Forgot to print the version: dolphin --version dolphin 23.08.1
Same bug on Fedora 38, dolphin-23.08.1-1.fc38. Downgrading to dolphin-22.12.3-1.fc38 is a workaround.
(In reply to Michael Eager from comment #7) > Same bug on Fedora 38, dolphin-23.08.1-1.fc38. > Downgrading to dolphin-22.12.3-1.fc38 is a workaround. This isn't an option on rolling release distro's like Gentoo where the earliest/stable release is 23.04.3, testing is 23.08.2.
