Error with picard 2.2 and classical extras plugin 2.0.6

[aereaux]

I updated the classical extras plugin to 2.0.6, and I can open the options menu without picard crashing, but when I add albums, I get this error repeated many times. Picard doesn't crash, but the albums appear red, and have a lot of fields missing.
