3.2beta3 Advanced search for Activity does not search "With"

I have added an activity to a few people's records. But when I do advanced search to find people with those activities added, the only record that matches is mine (presumably because I am one who ADDED the activity records).

The previous behaviour (3.1) seems to be to search for contacts that the activity is "with" – seems far more sensible. Also seems more logical since "with" is selected in the radio elements under the activity search part of the advanced search.

Work-around: put "%" in the contact search part of the activity search. This makes civicrm honour the radio option (where "with" is selected by default).
