[SOLVED] Thumbnail generator hangs 9.0.2

[Martin951]

Yes, "Encoded by": iTunes 8.1.1
Also true the files contain no cover images
They have 2 (two) COMMENT tags that break the id3v2 tag rules: The COMMENT field must be unique.

I, too, won't be able to test the files today, but if I can suggest anything: edit them, and remove all the irrelevant tags (their names are):
Comment, all those beginning with WM/..., File ID: taginfo1, iTunes_CDDB_IDs

thank you all for the comments - so then, lets assume this is now solved for this particular album, and I will see where the scanner hangs next. Maybe its not a bug but rather a feature that the scanner hangs, it forces me to review the tags.
