Thanks for the follow up Paul - I've had IDLwave users stuck on emacs 23.4
due to this bug.

I can confirm that the 0001-Avoid-GTK-3-crash-with-icons-and-masks.patch
patch fixes the crash problem on our systems.  Emacs is compiled to use gtk2
on these installations so despite the name, the patch successfully addresses
the problem for gtk2 as well as gtk3.  This is due to the elimination of the 
gdk_pixbuf_new_from_data() call on an XImage acquired from XGetImage() on
displays with more than 8 bits per pixel, something which affected emacs
regardless of whether it was compiled for gtk2 or gtk3.
