ImportError: cannot import name WSGIContext

I recently did a fresh in stall of Swift 1.4.8 on 12.04 LTS. The normal swift cli works fine, but as soon as I change the proxy-server.conf to include swift3 in the pipeline I get the error from the issue title. Here is the full stack trace:

And here is my proxy-server.conf:

[DEFAULT]
bind_port = 8080
user = swift

[pipeline:main]
pipeline = catch_errors healthcheck cache swift3 s3token authtoken keystone proxy-server

[app:proxy-server]
use = egg:swift#proxy
allow_account_management = true
account_autocreate = true

[filter:keystone]
paste.filter_factory = keystone.middleware.swift_auth:filter_factory
operator_roles = admin, swiftoperator

[filter:authtoken]
paste.filter_factory = keystone.middleware.auth_token:filter_factory
delay_auth_decision = 1
auth_port = 35357
auth_host = 192.168.50.249
auth_protocol = http
admin_tenant_name = service
admin_user = swift
admin_password = swift

[filter:cache]
use = egg:swift#memcache
set log_name = cache
memcache_servers = 10.10.10.7:11211,10.10.10.8:11211;10.10.10.4:11211

[filter:catch_errors]
use = egg:swift#catch_errors

[filter:healthcheck]
use = egg:swift#healthcheck

[filter:s3token]
paste.filter_factory = keystone.middleware.s3_token:filter_factory
auth_port = 35357
auth_host = 192.168.50.249
auth_protocol = http
admin_tenant_name = service
admin_user = swift
admin_password = swift

[filter:swift3]
use = egg:swift3#swift3

Any help would be great.

Same problem. I think it is too old swift version.
