As Etienne said, base_contact module is empty for trunk because we have removed this functionality (res.partner.contact object).
That's why we have removed this module from trunk. So this feature can not be consider anymore for trunk.
For 6.1 it's big improvement. 6.1 is stable version, We have consider only blocking point and small change for stable version (because partner are used their production database on stable version, If we done a big commit as a improvement then many problem will occurs on their production database).
So we can not consider this improvement for stable 6.1.
Hello Etienne and Stuart,

Anyways thanks for contributions.
Hope you will understand this procedure.
Thanks again!
