Without cache drivers i have no exceptions, but with pylibmc based cache backend looks there is some bytes based objects, which produces flanker exceptions...

Thanks @hellysmile, I'll have a look at this in the next day or so. Is an exception thrown when using a different django cache, like django.core.cache.backends.locmem.LocMemCache, or just with pylibmc?

[dmpayton]

@hellysmile Unfortunately, I'm unable to duplicate using django-pylibmc or django-pylibmc-sasl. Can you please post what your settings.CACHES looks like, as well as an example of how you're triggering the exception?

[hellysmile]

@dmpayton, i am using https://github.com/rdegges/django-heroku-memcacheify on heroku with Python 2.7.4 and an exceptions comes at django.contrib.admin form

@hellysmile This is an issue in flanker, and I've opened a ticket to try and get it resolved. For what it's worth, I've also run into this now.

mailgun/flanker#31

Since this isn't an issue in django-flanker, I'm going to close out this ticket. Thanks again!
