The patch in the branch you linked seems to fix the problem and it applies cleanly to v6.0.
Does it have bad known side-effects?

Title:
  stock inventory - wrong stock_moves if moves with prodlots and without
  exists for one  product and location

Status in OpenERP Addons (modules):
  In Progress

Bug description:
  the following code in
  stock/product.py
  does not distinguish between
  * select all move_lines without prodlots
  * select all move_lines with prodlot = null

  a query without prodlot returns all moves regardless if these have
  lots and not

  this gives very wrong results for inventory postings

  the fix is complex and for now I put in into the module
  http://bazaar.launchpad.net/~c2c/c2c-rd-addons/trunk/files/head:/c2c_stock_accounting/
  stock.py
  wizard/stock_fill_inventory.py

  I didn't want to patch stock/product.py because it might break some
  applications which rely on exaclty this behavior.

  258         if date_values:
  259             where.append(tuple(date_values))
  260         if 'in' in what:
  261             # all moves from a location out of the set to a location in the set
  262             cr.execute(
  263                 'select sum(product_qty), product_id, product_uom '\
  264                 'from stock_move '\
  265                 'where location_dest_id IN %s '\
