[development] WSOD Creating a Imagefield Widget In a Form

I am creating a form in a module, and one of the fields I need in the form is an image field . I ma trying to add an imagefield_widget, but whenever I go to display the form, I get a wsod (white screen of death for the uninitiated) and the following error in my apache error logs: Tue Nov 17 07:16:05 2009] [notice] child pid 19512 exit signal Bus error (10) I have included the imagefield_widget.inc file since that's where the widget definition is. Anybody know why I'm getting this? I'm using MacPorts on Snow Leopard. Thanks. Steve
