Users with non-english locale cannot add events.

This is a duplicate of event.module issue http://drupal.org/node/29452 , but I guess it really is a flexinode issue. Short description:

When I upgraded from drupal (and event) 4.5 to 4.6, regular users could not add events. I run with a norwegian locale. Regular users can add events only if they change their locale to english. The admin user can still add events as usual, regardless of locale.
