[Khan-Dam]

Hi,

I've just put the upgrade to 0.8.16 Version and i've a big probleme with this version.

When i try to update metadata with cliking the Button i obtain this messages :

calibre, version 0.8.16
ERROR: Exception non gérée: <b>KeyError</b>:'author_name_copywords'

Traceback (most recent call last):
  File "site-packages\calibre\gui2\metadata\basic_widgets.py", line 356, in update_state_and_val
  File "site-packages\calibre\ebooks\metadata\__init__.py", line 70, in authors_to_sort_string
  File "site-packages\calibre\ebooks\metadata\__init__.py", line 41, in author_to_author_sort
KeyError: 'author_name_copywords'

i click OK then :

calibre, version 0.8.16
ERROR: Exception non gérée: <b>KeyError</b>:'author_name_copywords'

Traceback (most recent call last):
  File "site-packages\calibre\gui2\metadata\basic_widgets.py", line 356, in update_state_and_val
  File "site-packages\calibre\ebooks\metadata\__init__.py", line 70, in authors_to_sort_string
  File "site-packages\calibre\ebooks\metadata\__init__.py", line 41, in author_to_author_sort
KeyError: 'author_name_copywords'

and now i show the form correctly
if i choose another author in the combo another time i hace the message :

calibre, version 0.8.16
ERROR: Exception non gérée: <b>KeyError</b>:'author_name_copywords'

Traceback (most recent call last):

  File "site-packages\calibre\ebooks\metadata\__init__.py", line 41, in author_to_author_sort
KeyError: 'author_name_copywords'

You are mixing code from two different calibre releases. Look for the file default_tweaks.py on your computer and delete it wherever you find it outside the calibre installation directory.

Thank you for That
