No replies, but I have some more info. The gtk2 clients that segfault 
going from LDVS to VGA show

#0  init_xinerama_support (screen=<value optimized out>) at

#6  0xb78aadcf in ?? () from /usr/lib/

should gdk_x11_screen_size_changed be calling init_xinerama_support?

Are there known issues between rand1.2 and gtk/gdk?
