Account and Contact fieldmaps with user - account gets ignored

Hi! I have been pulling my hair over this... I have 2 fieldmaps, Account and Contact sf objects, both connected to the drupal user object. It tries to first sync the account, but I receive an error: soap tries to connect to the Contact account instead of the user.
The crazy part: Right before the $sf->soap call, fieldmaps AND object type look as expected. (right account fieldmap and object type = account). But soap tried to connect the field maps with Contact, not Account object!

After that, contact fieldmap uses contact object, and this sync works fine. Any ideas at all???
