I think I might have found a couple of more bugs

1. Certain albums will refuse to show under the Albums view, even though they show just find under Artists view ( after you have selected the artist, that is ) . The pattern I am noticing is Albums that have non-unique names. I have checked the ID3 tags and they are okay and Canola recognizes them without problems.

2. If the .thumbnails directory is deleted, it is not created again. Attempting a cleanup, I deleted .mediabox and .thumbnails - I got no album covers after starting MediaBox. However after I created .thumbnails manually, and restarted MediaBox , the covers came back.

What all things do I need to delete to do a perfect cleanup ?
