3012	Traceback when using locmem cache backend	Alex Dedul	Jacob	"A couple of months or so ago i started to get this traceback on sequential reloads of specific page. Seems it also affects other users, there is notice of it here http://simon.bofh.ms/logger/django/2006/10/08/ (search for 'not safe'). Running latest trunk here. I can give any additional info if needed. Would like to debug it myself but my knowledge of django internals is not so good for this..
