Hi,
I've added some tests, visible in this branch lp:~openerp-dev/openobject-server/trunk-in-not-in-m2m-tests-vmt.
I think I have covered the case you give in this bug report. I can't reproduce your situation.
If you think there is still a problem, please add a test case to examplify it and re-open the bug report (I will close it now).
