clients die on xrandr 1.2 switch

[Ken Mandelberg]

I'm now running on Ubuntu Feisty with

X Window System Version 1.3.0
X.Org Video Driver: 1.2

on a 915GM laptop.

xrandr 1.2 switches "work", the Gnome desktop switches between the 
1024x768 LVDS and a 1920x1200 VGA and resizes.

In the VGA->LVDS switch all the clients survive.

In the LDVS->VGA switch the gnome-terminals always segfault. It's hit 
and miss on other clients. xterms survive.

Am I missing some library updates that need to be xrandr savvy?
