rAudio 20250627: Update Thumbnails - Conversion failed

[klassikmann]

If I make a (local) "Update Thumbnails" -> "Only added or removed" and one of the affected directories has (intended) no folder.jpg I get a "Coversion failed" message:

!  Coversion failed:
/mnt/MPD/NAS/Musik/Alte Musik/Lully, Jean-Baptiste/Armide (Revision 1778)/folder.jpg

magick: unable to open image '/mnt/MPD/NAS/Musik/Alte Musik/Lully, Jean-Baptiste/Armide (Revision 1778)/folder.jpg': No such file or directory @ error/blob.c/OpenBlob/3596.

Issue vanished, probably my fault.
