I am using Calibre 0.8.60 on OSX and version 1.1.2 of the plugin. I have tried installing it both through the plugin manager and also the manual way with the zip file. Every time I install it, though, I end up with 2 copies of the plugin in my plugin manager. When I do metadata downloads it always says that it's downloading from "Goodreads, Goodreads, Google, Amazon.com, ISBNDB". I have tried disabling one copy of the plugin to make it only use the plugin once, but disabling one of them seems to disable both.
Downloading from Goodreads twice wouldn't really be too much of an issue, I guess, except that it always gives me an error when it gets to the cover download part. Here is the error:
Traceback (most recent call last):
File "site-packages/calibre/utils/ipc/simple_worker.py", line 208, in main
File "site-packages/calibre/ebooks/metadata/sources/worker.py", line 125, in single_covers
OSError: [Errno 17] File exists: 'Goodreads,,290,,475,,jpeg.cover.done'
Any suggestions on how I might get only one copy of this plugin installed?
