Dolphin will not drag and drop

English Applications
1

Recently, Dolphin freezes when trying to drag and drop files within or between panes. Happens with both ext4 and NTFS file systems. When started in a terminal it says:

howard@HP-oS160:~> dolphin
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.")
howard@HP-oS160:~>

What’s the problem?
Thanks,

This topic is tagged Leap 15.6. Which version you are using?

Got a bunch of updates this morning, including new nVidia driver, and the problem seems to be fixed.

Spoke too soon. Dolphin sometimes works, more often does not. Latest failure gave in terminal:

howard@HP-oS160:~> dolphin
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.")
KCrash: Application 'dolphin' crashing... crashRecursionCounter = 2
Aborted (core dumped)

Any ideas?

Thanks. I tried to find a way to correct the tag myself, but concluded I was not authorized.
