[Glade-users] Sharing a File Chooser Dialog Box -> Segfault? - SOLVED

[dswain at princeton.edu (Dan Swain)]

I managed to find a solution myself.  I discovered that this was occurring
no matter what kind of window was added to my glade project.  The solution:
Change the return type of the button_press_event that handles the
gtk_popup_menu to gint instead of gboolean.
