Album artwork impacted by .AppleDouble sub folders on NAS

[audiobeer]

Hi there,

I have a small issue that I believe is related with this:
Every other albuns I have there's some extra information, like cue files, artwork, log files etc... Usually I put all of those in a subfolderc inside the album folder. Something like:
Artist > Album Subfolder > Extra subfolder

I found that anytime there's an subfolder the thumbnail art fails.

Well, my workaround at this stage is to have an .mpdignore inside every album in order to ignore any "Extra" subfolder. But I question if this is intended behaviour or is it a bug?

Thanks in advance
