Comment 3 for bug 615274

I've spent 3 hours trying to get useful information about this.

It's <email address hidden>

In the loop of 'for r in obj.pool.get(self._obj)._read_flat(cr, user, ids2, [self._fields_id], context=context, load='_classic_write'):'
it tries to append an id of an act_window that's not in res.

I tries removing the act_window in question but then it just fails with another act_window_id.

Don't know how to reproduce it with another db but I can't give you my whole db, it's not test data.
