the problem is, that the
config_get_access( 'notify_flags' );
and
config_get_access( 'default_notify_flags' );
calls in manage_config_email_page.php do not return the values which are actually stored in the db - they allways return 90 (administrator threshold)

i had a look into config_get_acces (core/config_api.php) .. i do not understand why this functions loops over the project and user list, i guess there is a reason, but it does not really work since the line 186 (1.0.0rc1)
$t_access = $g_cache_config_access[$p_option][$t_user][$t_project];
allways results in
$t_access = $g_cache_config_access[$p_option][0][0];
when called from manage_config_email_page.php

i had a try with this dirty hack:
$t_access = $g_cache_config_access[$p_option][auth_get_current_user_id()][helper_get_current_project()];
but it had bad sideeffects since anybody seemed to be able to do anything..

Fixed in CVS. I missed this when I did the performance tweaks.

core/config_api.php -> 1.34
