RE: Casting GTKWidgets - Urgent

["Dugas, Alan" <alan dugas analog com>]

It's basically telling you that the argument it receives is a NULL pointer
and not a GtkEntry.  If user_data is just data and not a widget, then you
are not setting the right function argument to text_entry and therefore
GTK_ENTRY().  If so, I believe the following should fix your problem;

GtkWidget *text_entry = editable;
