I set sessions storage type to memcached in production and received this
error as a result:
{{{

}}}

OS is FreeBSD 8. Relevant packages installed:

{{{
py27-cherrypy-3.2.0
py27-memcached-1.47
python27-2.7.1_1
}}}

For now I set the storage type to ram as a workaround since I only have a
single process going.

MemcachedStringEncodingError when using
memcached sessions storage type

Comment:

Attached is patch against trunk (r2829) that fixes this for me. I did not
test on pythons other than 2.7.
