Error when we try to create a refund

[Romain Deheele - Camptocamp]

Hello,

I create a RMA.
I attach an invoice : partner delivery address and claim lines are populated correctly.
I pass the RMA in state progress.
I click on "New Refund" button.
It raises the next error :
  File "/home/rdeheele/oerp/sandbox/parts/addons/account/wizard/account_invoice_refund.py", line 232, in invoice_refund
    data_refund = self.read(cr, uid, ids, ['filter_refund'],context=context)[0]['filter_refund']
  File "/home/rdeheele/oerp/sandbox/parts/openerp-rma/crm_claim_rma/wizard/account_invoice_refund.py", line 36, in compute_refund
    cr, uid, ids, mode=mode, context=context)
  File "/home/rdeheele/oerp/sandbox/parts/addons/account/wizard/account_invoice_refund.py", line 158, in compute_refund
    refund_id = inv_obj.refund(cr, uid, [inv.id], date, period, description, journal_id, context=context)
  File "/home/rdeheele/oerp/sandbox/parts/addons/account/account_invoice.py", line 1268, in refund
    context=context)
  File "/home/rdeheele/oerp/sandbox/parts/openerp-rma/crm_claim_rma/account_invoice.py", line 87, in _prepare_refund
    journal_id=journal_id, context=context)
  File "/home/rdeheele/oerp/sandbox/parts/addons/account/account_invoice.py", line 1232, in _prepare_refund
    invoice_lines = self._refund_cleanup_lines(cr, uid, invoice.invoice_line, context=context)
  File "/home/rdeheele/oerp/sandbox/parts/openerp-rma/crm_claim_rma/account_invoice.py", line 49, in _refund_cleanup_lines
    for __, claim_line_id in context.get('claim_line_ids'):
ValueError: too many values to unpack
