This error occurs when you’re trying to add an item to the playlist which does not exist anymore.
It should NEVER happen when you add the items directly from the library browser.
Copy the playlist into the clipboard (select all items, press Ctrl+C), paste it into a text editor, and search for the string “19422”, appearing in the DatabaseID context. This should help you identify the broken item.
The funniest part of this issue is when i am using version 1122 i do not have this problems. I am working on the original database of version 3 . I have upgraded the database scvhema to version 18 So i do not know what is causing this . I did have deleted some double songs in the database tonight…
