[gedit-list] Any way for a plugin to know when gedit is quitting?

[Micah Carrick <micah quixotix com>]

Is there any way to know when gedit is quitting (from File > Quit) *before* the tabs are removed from a plugin? I tried connecting to the Quit action's "activate" signal but the plugin's do_deactivate() is called (and thus signal disconnected) before my signal handler can be called.
