gnome_popup_menu

[Timo Sirainen <aaaaaa sicom fi>]

gnome_popup_menu_do_popup() has "g_return_if_fail (event != NULL);" even
when it's made to work with NULL event.

And is the gtk_popup_menu_do_popup_modal() useful for something? After
opening menu item with it, it leaves the mouse buttons in some weird
state, I need to click around the screen to make it work again.
