Hi folks

Sometimes, I got "SQLAlchemy raises None, causes TypeError"
This get debugging hard, because it hides real reasons.

It looks like the problem of combining eventlet and sqlalchemy.

Latest version of sqlalchemy looks improved of this exception handling code.

The sqlalchemy version looks pinned to
sqlalchemy>=0.7.8,<=0.7.99.

Because we needed SqlSoup (see [1]),
However sqlsoup is no longer used.

so I would like to upgrade sqlalchemy, but
if the other project needs 0.7 version, please let me know.

    pin sqlalchemy to 0.7

    The sqlalchemy package 0.8.0b1 released on October 30, 2012
    removed SQLSoup

    (http://docs.sqlalchemy.org/en/latest/changelog/migration_08.html#sqlsoup)

    Ensure that the SqlSoup import is still supported. A number of
quantum agents
    make use of this code to access the database.
