Issue1671431

With latest beta 2.2 (source revision 3133) I have created database connection object as follows: 

dbConn = zxJDBC.connect(uri, username, password, driver)

However subsequent dir(dbConn) causes following exception

AttributeError: 'list' object has no attribute 'keys'

Exception should not be thrown as dir(x) is expected to work with any Python object.

Fixed in r3189.
