[web2py] problem with 1.77.3 & 1.78.3 and legacy database

[drayco]

Hi, I updated my web2py, but I had a problem with web2py 1.78.3, I use
legacy databases. When I try to go to my application I got this

Error traceback

Traceback (most recent call last):
  File "/media/RESPALDO/web2py/gluon/restricted.py", line 178, in

calenergy=SQLDB('mysql://xxx:x...@127.0.0.1:3306/xxx',pool_size=10)

calenergy.define_table('area',
        Field('clave', type = 'char' , length = 3 ),
        Field('IdZona', type = 'integer' , length = 10 ),
        Field('nombre', type = 'string' , length = 50 ),
        primarykey=['clave','IdZona'],
        migrate = False)

Even with web2py 1.77.3.

What this mean?

with my older version of web2py, I work well.
