Description of problem: X session has crashed, while the machine is
running idle, with Xscreensaver being active. GDM restarts and I'm
placed with a login screen, with all other running X apps dead.


Version-Release number of selected component (if applicable):
kernel-2.4.22-1.2188.nptl
XFree86-4.3.0-55
gdm-2.4.4.5-1.2

How reproducible:
So far, this has only happened once - looks like a screensaver within
the xscreensaver package that is causing grief. Only noticed after the
new kernel upgrade.

Steps to Reproduce:
1. Leave machine idle
2. Xscreensaver starts
3. (Xscreensaver possibly hits a buggy screensaver)
4. GDM crashes
  
Actual results:
GDM restarts, placing me at the login screen. All work in X that was
running earlier has been lost

Expected results:
Xscreensaver showing the password unlock screen
