Description

py27-sqlalchemy @1.4.1_0 broke our buildbot-0.8 setup. I had to go back to py27-sqlalchemy @1.3.23_0 to prevent this from happening on buildmaster startup:

$ sudo -u buildbot env HOME=/opt/local/var/buildmaster TZ=UTC /opt/local/bin/twistd-2.7 --nodaemon --no_save --python=buildbot.tac
:0: UserWarning: You do not have a working installation of the service_identity module: 'No module named service_identity'.  Please install it from <https://pypi.python.org/pypi/service_identity> and make sure all of its dependencies are satisfied.  Without the service_identity module, Twisted can perform only rudimentary TLS client hostname verification.  Many valid certificate/hostname mappings may be rejected.

Don't know if this is a bug in py-sqlalchemy or if buildbot-0.8 needs to be changed in some way to accommodate a py-sqlalchemy change.

I'm not very familiar with python but a quick search suggested that unexpected object has no attribute messages might indicate a circular dependency between python files that include each other.
