Could not load album ssbsbdbf-sndnn5-dffhgh

I keep getting this type of response in Picard when I try to look up an album.

What is this?

Is it in response to an album that was previously tagged and had an album ID embedded in the tags? I had this when I re-scanned some albums that were originally tagged years ago. In the interim some of the albums had been merged with other releases, and I needed to look up the new release and match the album to it. If it’s not the case, can you give a specific example of an album that fails to load?

It might also be that the release is just failing to load because of some issue with the web service.
