This is a bug in python-memcached.  Under some circumstances, 
_val_to_store_info() returns 0 (see line 713), yet set_multi(), line 
643, is not prepared to handle that return value.  You would be doing a 
good service if you reported this to the authors.

I always use pylibmc.  It's slightly harder to set up, but in my 
experience, it's fast and reliable.  If you use it, be sure to use the 
wrapper from the relstorage package.  The wrapper ignores memcached 
connection problems.  See the zodbshootout buildout.cfg for a way to 
install libmemcached and pylibmc using only Buildout.

See the [libmemcached] and [pylibmc] sections in particular.
