I have found a weird issue in in v6.1:

If I modify 'quantity' field by inheriting class 'account_invoice_lines' from 'account' module to modify its decimal precision seems to break account_invoice_report view whenever I start OpenERP with --update=all.

The actual line that triggers the issue is modifying 'quantity' with: 

digits_compute=dp.get_precision('Product UoS')),

Facts I have checked:

• That digits_compute works fine in other fields.
• Yes, 'Product UoS' decimal precision is defined and set to 3 or 6, doesn't matter.
• I have cloned account_invoice_report with some added fields... and works fine with such decimal precision change.
• It looks like account_invoice_report view should be deleted and rebuilt on every --update=all, but with this (naive) change, something breaks in the middle and prevents its creation. Such creation error leaves no log.

The issue happens when:

• Go to 'Settings > Reporting > Statistic Reports > Invoices Analysis'
• or eneter in Sales main board with "Monthly turnover" graph.

So... Any clue???

Error trace raised when trying to load account_invoice_report view:
