g-api complaining about 'connection_errors' in 'RabbitStrategy'

Hello!

When I tried to setup a new devstack this morning, the script 'stack.sh' failed on starting glance-api.

Log:
+ screen -S stack -p g-api -X stuff 'cd /opt/stack/glance; /usr/local/bin/glance-api --config-file=/etc/glance/glance-api.conf '| touch "/opt/stack/status/stack/g-api.failure"
+ echo 'Waiting for g-api (192.168.42.16:9292) to start...'
Waiting for g-api (192.168.42.16:9292) to start...
+ timeout 60 sh -c 'while ! http_proxy= wget -q -O- http://192.168.42.16:9292; do sleep 1; done'
+ die 191 'g-api did not start'
+ local exitcode=0
+ set +o xtrace
[ERROR] stack.sh:191 g-api did not start

I then tried to start glance-api manually:
/opt/stack/devstack$ cd /opt/stack/glance; /usr/local/bin/glance-api --config-file=/etc/glance/glance-api.conf

After some debug lines, I got a critical error: 'RabbitStrategy' object has no attribute 'connection_errors'

Considering this bug only seems to affect me, and git is up-to-date on my computer, have you any ideas of what could cause this error?

Thanks in advance!
