Hi, new Fedora user. Coming from Kubuntu and most everything seems running smoothly.
Running Fedora 41 KDE spin. Single user machine (administrative account disabled on install), everything kept updated. A few days ago Dolphin started to freeze up for several seconds to minutes when doing file operations like copy and cut, and sometimes even when launching (it will not display any contents like files and folders). The strange thing is that sometimes it does it and others I can have my PC running for hours with no issue. Looking at the jounald logs I get this when Dolphin 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.")Oddly enough, this does not happen when I enable “act as administrator” in Dolphin View options.
After some extensive googling I found some old (and others recent) posts about unresolved bugs in xdg-desktop-portal. Eventually I found that the service “xdg-document-portal” was (apparently) the cause of the problem for me. Killing the process unfreezes Dolphin (with no apparent side-effects). Today Dolphin froze several times, each time I managed to fix it by killing xdg-document-portal and letting it restart.
Has anyone experienced similar issues? Is it fixable? What could be causing it? All the google posts I have seen that are vaguely related have to do with flatpaks and permission issues with /run/user/1000/doc. I don’t have flatpaks installed (though Fedora does have the whole flatpak subsystem enabled by default).
