Having a bit of an annoying issue lately. OS is Fedora 41 KDE spin. Single user system with Administrator account disabled from install. This has been happening for a few days now and I don’t really remember any change that I did on my OS software wise or with configurations that may have caused a problem. Basically Dolphin will freeze and become unresponsive for several seconds (sometimes up to minute) if I either launch it (window appears but does not display files/folders) or right click copy/cut. Not always, as I can usually go for hours without this issue, but then all of a sudden it happens. Running Dolphin from a terminal I get this after it becomes unstuck:
kf.coreaddons: Some files could not be exported. QDBusError("org.freedesktop.DBus.Error.NoReply", "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.")This sometimes also causes my Plasma panel to become unresponsive. Surprisingly enough, I can avoid it getting frozen by enabling administrator mode from Dolphin View options.
I did some googling and it led me to all sorts of places (won’t bore you with those details) but eventually found out that the xdg-document-portal service was causing this. Every time Dolphin would freeze, if I kill the xdg-document-portal service and let it restart Dolphin becomes responsive again immediately (same with the Plasma panel).
What can be causing this and does it have a proper fix? I don’t use flatpaks or snaps, just plain old .rpm packages from Fedora and rpmfussion. A permission issue perhaps (seeing as how Administrator Mode does not have this problem)? Something went haywire with xdg-desktop-portal packages (I have been reading they can be buggy for some people)?
