Comment 3 for bug 1127198

This was originally fixed in v6.0 on rev 5380
http://bazaar.launchpad.net/~openerp/openobject-addons/6.0/revision/5380

It says there that this was a backport from 6.1 but I cannot find that mentioned revision id at all.

If my memory is correct we originally reported this issue.

Mind you this solution is not complete as the voucher itself is still using the date from the imported invoice!
