I really like this plugin and I would like to ask why I get this error:
****
calibre, version 7.4.0
ERROR: Unhandled exception: <b>UnboundLocalError</b>:cannot access local variable 'book_dict' where it is not associated with a value

calibre 7.4 embedded-python: True

Since I have many authors, I select a few of them and at some point I get the specified error. After that nothing happens anymore and I have to select Cancel. What happened until then he collected Ok.
