1212	Button Printf Callback Fails	guest	somebody	"The version was 0.12 (not listed as an option).

If I include any call to printf (from Text.Printf) within a button callback, I get a ""gtk2hs_closure_marshal: uncaught exception"" and the program terminates.  The failure does not seem to happen with other non-button callbacks and it also does not fail for other string printing functions like putStrLn.

The equivalent code in C works fine.  I've attached both a C and haskell version for comparison."	defect	new	normal		general (Gtk+, Glib)			printf button callback
