Imaginary tax on the shipping amount!

[Romain Deheele - Camptocamp]

Hello,

In my magento, I have an order without tax.
one product with 16.50 €
+ shipping and handling : 4.18 €
TOTAL : 20.68 €

When I import this order in OpenERP, it adds a tax on the shipping amount.
Tax on the shipping amount : 0,82 €
TOTAL incl. tax : 21.50 € !!

If i do a print on data (in the def mage_import_base in magerp_osv.py), I can see these variables :
 'shipping_tax_amount': '0.8200'
 'base_shipping_tax_amount': '0.8200',

It's bizarre that the plugin creates ex nihilo this tax on the shipping!

THanks for your help,

Romain
