I see this message a lot whe there are no covers available.
Code:
openlibrary.org covers - ISBN: 9780440244172 not found
Douban.com covers - tuple index out of range
librarything.com covers - ISBN: 9780440244172 not found
What the heck is "Tuple out of range"?
I see this, even when (about 5 versions ago) I disabled the Douban plugin
