[web2py] is_jdbc is not defined erro when running with App Engine

[gus]

Hi all...

Just trying to deploy Version 1.96.4 (2011-06-11 14:22:41) in App
Engine and I am receiving the following error

ERROR    2011-06-14 04:23:45,326 restricted.py:156] Traceback (most
recent call last):

applications/welcome/models/db.py", line 9, in <module>
    db = DAL('google:datastore')              # connect to Google
BigTable

    raise RuntimeError, "Failure to connect, tried %d times:\n%s" %
(attempts, error)
RuntimeError: Failure to connect, tried 5 times:
global name 'is_jdbc' is not defined

It seems that this var is not defined or set False when the db is
'google:datastore'. If it is defined as False it works perfectly. What
seems odd is that the var is barely used, so I am wondering if this
may be a problem with my configuration.

Thanks in advance
