Hello, I use SQLAlchemy 0.7.5, Python 3.2.2 and MySQL connector 0.3.2-
devel (https://launchpad.net/myconnpy). Accordind to website, MySQL
connector should be supported. But I get this exception:
Traceback (most recent call last):
File "/usr/local/lib/python3.2/dist-packages/sqlalchemy/pool.py",

File "/usr/local/lib/python3.2/dist-packages/sqlalchemy/util/
queue.py", line 137, in get
raise Empty
sqlalchemy.util.queue.Empty
During handling of the above exception, another exception occurred:
