Fatal error: Call to undefined function: ()

Hi,

I created 2 civiCRM profiles earlier when i was using civiCRM version 1.5, one has no mandatory field, where as one has some mandatory fields. I am using both forms as standalone forms. In version 1.5 when i try save the profile which has some manadatory fields, without filling complete form, it was giving error message to fill the data in mandatory fields, but now when i upgraded civicrm 1.5 to CiviCRM 1.7.beta.9239 , the same form is giving

Fatal error: Call to undefined function: () in /home/thinkind/public_html/den/modules/civicrm/CRM/Profile/Form/Edit.php on line 266

when i try to save form without filling mandatory fields. The same form saves perfectly fine if i fill all manadatory fields.

The other profile form which has no mandatory fields, saves fine when i dont fill any data in any field.
