Thanks! for the clarification.

I tried to go back to digiKam4, but the corresponding libkipi packages 
wouldn't compile. So I reinstalled digiKam5 and updated some other 
stuff. And now the dbus errors have disappeared.

In digiKam5, even after reinstalling moving tags from one location to 
another location on the tag tree still sometimes fails, and always with 
the same tags. I think the relevant terminal output is as follows:

digikam.general: Delete Shortcut assigned to tag  76
digikam.dbengine: Failure executing query:
   "UPDATE Tags SET pid=? WHERE id=?;"
Error messages: "Unable to fetch row" "UNIQUE constraint failed: 
TagsTree.id, TagsTree.pid" 19 1
Bound values:  (QVariant(int, 184), QVariant(int, 76))
digikam.general: Delete Shortcut assigned to tag  12
digikam.dbengine: Failure executing query:
   "UPDATE Tags SET pid=? WHERE id=?;"
Error messages: "Unable to fetch row" "UNIQUE constraint failed: 
TagsTree.id, TagsTree.pid" 19 1
Bound values:  (QVariant(int, 184), QVariant(int, 12))
digikam.general: Delete Shortcut assigned to tag  80
digikam.dbengine: Failure executing query:
   "UPDATE Tags SET pid=? WHERE id=?;"
Error messages: "Unable to fetch row" "UNIQUE constraint failed: 
TagsTree.id, TagsTree.pid" 19 1
Bound values:  (QVariant(int, 184), QVariant(int, 80))

So I transferred the subtags of the "unique constraint"-affected tags to 
where they ought to be by creating a new tag in the correct location, 
and moving the subtags from the old tag to the new tag. Hopefully this 
"unique contraint" issue won't happen again.

I have icons for all my other KDE applications, but still not for 
digiKam5. I gave IceWM the exact path to the breeze icon for digiKam 
(shouldn't be necessary), and also tried the exact path to the oxygen 
icon, and either way still the digiKam icon is just the red X.

Best,
