Not able to get content profile user registration to work

Using:
drupal-6.16
cck-6.x-2.6 with groups
content_profile-6.x-1.0
legal-6.x-2.2-beta4
reg_with_pic-6.x-1.7

Using:
Mandotory fields -> cck-date, one cck-location and one cck-checkboxes field
No optional fields

Tried so far:
Giving anon access for profile creation
removing cck groups
removing validation in form_alter
removing location mandotory field and using node location instead
removing trigger actions on user creation

No errors!
The content profile is simply never created even though all the fields are shown correctly with validations during registration.

Would appreciate any pointers.
