Investigating further with debug on, I get this when closing the window 

Calling (gtk-widget-destroy #.(SB-SYS:INT-SAP #X080AA848))
  (gtk-widget-destroy #.(SB-SYS:INT-SAP #X080AA848)) returns NIL

Then after c-c and selecting restart "give-up-cleanly", some more widgets are 
destroyed (my menu I guess) then I get this endlessly:

Calling (gtk-main-level )
  (gtk-main-level ) returns 1
Calling (gtk-main-quit )
  (gtk-main-quit ) returns NIL
Calling (gtk-main-level )
  (gtk-main-level ) returns 1
Calling (gtk-main-quit )
  (gtk-main-quit ) returns NIL

Looks like my gtk+ library is 2.8.20
