Flag does not work with Activity 2

Flag 6.x-2.0-beta1 is not compatible with Activity 6.x-1.2

When activity_install_activity_defaults($module='flagactivity') (in activity/activity.module) by flagactiivty_install(),

it does not return a 'types' array, so the following line fails because it's NULL:

Line: 1053: variable_set($module .'_token_types', array_keys($info['types']));

where $info =
