I use two libraries. In one of them I successfully created an On Device list and populated it from my kindle. I tried adding and removing books from the reader and the plugin populated my custom column correctly when I synced afterwards.

But I can’t get the plugin to work with my other library. Clicking on the icon gives me error:

Spoiler:

calibre, version 0.8.27
ERROR: Unhandled exception: <b>KeyError</b>:u'listType'

Traceback (most recent call last):
File "calibre_plugins.reading_list.action", line 234, in about_to_show_menu
File "calibre_plugins.reading_list.action", line 80, in rebuild_menus
File "calibre_plugins.reading_list.config", line 205, in get_list_names
KeyError: u'listType'

Switching from the working library to the non-working I get the error:

ERROR: Unhandled exception: <b>KeyError</b>:u'listType'

I tried to remove the plugin(Reading List.json as well) and re-add, but get the same error.
EDIT: I apparently only thought I'd tried this. Removing the .json makes it possible to use the beta with both libraries.
