11640	1.1 Test framework fails if CACHE_BACKEND = dummy	fgasperino	Dan Loewenherz	"
1.1 seems to fail built-in contrib/sessions/test.py if the cache api is enabled, but set to dummy.

CACHE_BACKEND = 'dummy:///'
#CACHE_BACKEND = ""locmem:///?timeout=300&max_entries=1000""

vs 

#CACHE_BACKEND = 'dummy:///'
CACHE_BACKEND = ""locmem:///?timeout=300&max_entries=1000""
