I have a problem with my db tables definition. In db.py file there seems to be a problem with the table with name "NFCobj". I get the "<class 'cPickle.UnpicklingError'> pickle data was truncated" error If I have the db.define_table command, with table name "NFCobj" like this:

#NFCobj table
db.define_table('NFCobj',
    Field('name','string',required=True),
    Field('href','string', required=True),
    Field('active','boolean'),
    format='%(name)s'
)

when I change the name to for example "NFobj", everything is OK:

#NFCobj table
db.define_table('NFobj',
    Field('name','string',required=True),
    Field('href','string', required=True),
    Field('active','boolean'),
    format='%(name)s'
)

I have already tried to delete all web2py directory, and reinstall a new fresh installation, got the last working version of the application from the bitbucket, still cant solve this issue.

 It seems that there are some temp data or something else left somewhere on the local PC where I'm testing this application. Tommorrow I will try to run the same application from different computer. I predict that I won't be able to repeat this issue on fifferent PC.

Please can somebody help me resolve this issue?
