Exceptions with the wrong IDs

[fhriley]

I did a full library rescan with this plugin, and I'm seeing weird exceptions where it looks like it's querying with the wrong IDs:

One of those is clearly an IMDB ID. I don't know what EP01216702 is. And it also tried to use an ID of null. Is there a race condition perhaps where it is occasionally trying to use the wrong ID?
