I've been having issues with whoosh in combination with django-haystack. About once a week, the website running haystack and whoosh keeps returning errors and filling our Sentry feeds with the following error:
whoosh.util.cache in wrapper KeyError: (<CompressedBytes.Reader>, 1L)
(1L changes, full stacktrace here: http://pastebin.com/cMRKhxpR )
I was wondering if this is something that (could be) related to whoosh or our implementation of it. If you have any idea on how to fix this it would be very helpful.
