I'm facing an error when importing data from an excel file using a wizard, but this error only occurs in allinone installation of openerp 6.1 The error is related with base64 and console shows "Padding error".

Since it doesn't occurs in development enviroment, I don't know what to do...

I get the excel file using a binary field in a wizard, then I try to decode it: decode_file = base64.b64decode(excel)

  and then is when  that error occurs

Like I said, in ubuntu and windows development enviroments there is no problem, but in allinone installation a padding error raices.

Any help thanks in advanced.
