Today I noticed that my syslog had quickly grown to 8GB in size, filled with repeating log spam caused by cutting and pasting a file in Dolphin. (First, there seems to be some debug output remains from Dolphin ("true, actions, urly") which isn't the problem but does normally occur sometimes in log output.) The main problem is four repeating lines from kf.coreaddons,kf.coreaddons,qt.dbus.integration,kf.coreaddons, spammed dozens (or hundreds) times per second: dolphin[5737]: true dolphin[5737]: actions!!! dolphin[5737]: true dolphin[5737]: actions!!! dolphin[5737]: urly!!! QUrl("admin:///mnt/SSD/some/folder somewhere/") dolphin[5737]: kf.kio.workers.file: copy() QUrl("file:///home/ntt/Lataukset/Screenshot 2024-04-17 something.png") to QUrl("file:///mnt/SSD/some/folder somewhere/Screenshot 2024-04-17 something.png") mode= 420 dolphin[5737]: kf.kio.workers.file: copy() QUrl("file:///home/ntt/Lataukset/Screenshot 2024-04-17 something file 2.png") to QUrl("file:///mnt/SSD/some/folder somewhere/Screenshot 2024-04-17 something file 2.png") mode= 420 plasmashell[3799]: kf.coreaddons: Failed to open "/home/ntt/Lataukset/Screenshot 2024-04-17 something.png" Tiedostoa tai hakemistoa ei ole plasmashell[3799]: kf.coreaddons: Failed to open "/home/ntt/Lataukset/Screenshot 2024-04-17 something file 2.png" Tiedostoa tai hakemistoa ei ole plasmashell[3799]: qt.dbus.integration: QDBusConnection: error: could not send message to service "org.freedesktop.portal.Documents" path "/org/freedesktop/portal/documents" interface "org.freedesktop.portal.FileTransfer" member "AddFiles": Marshalling failed: Invalid file descriptor passed in arguments plasmashell[3799]: kf.coreaddons: Some files could not be exported.

QDBusError("org.freedesktop.DBus.Error.Failed", "Marshalling failed: Invalid file descriptor passed in arguments") . . . "Tiedostoa tai hakemistoa ei ole" in the log output means File or forder does not exist. Closing Dolphin seems to stop the log spam. Seems like a regression after KDE6 upgrade, I didn't notice it before. Operating System: KDE neon 6.0 KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.1.0 Qt Version: 6.7.0 Kernel Version: 5.15.0-102-generic (64-bit) Graphics Platform: Wayland
I'm facing the same issue which I've only noticed by degraded system performance due to plasmashell using 30% of CPU. I've looked at journalctl and saw repeated lines same as other reporter. Closing Dolphin ceased the log spam and increased CPU usage.

Same problem here. Especially after cut and paste files to a NFS mount. 50% cpu until I close Dolphin. Same output in the journal. Arch + Wayland, KDE up to date.
