The error handling for loading errors on albums, non-album tracks and files is currently all very different:
- Albums show errors in info dialog, tracks and files not
- In itemviews tracks show error as tooltip, albums show a general message (since
PICARD-2035), files show nothing
- Albums can potentially handle multiple errors (e.g. due to plugins), tracks and files not
- If an album shows errors, the normal info tab in info dialog is hidden
This should all be unified and errors been shown in a separate tab of the entities info dialog.
