Script to do the crash.

User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:6.0) Gecko/20110815
Firefox/6.0 SeaMonkey/2.3

I can crash my X-server with a reproducable scenario. I have prepared a script.
A core dump is also available (on request, gdb-gcore-created, bzip: ~6 MB.



Reproducible: Always

Steps to Reproduce:
(from head of the script)
# To reproduce the error:
# - dual head/display configuration ( 1920x1200 )
# - configured as one display only
# - configure with xrandr as dual screen
# xrandr --fb 3840x1200 --output DVI-0 --output VGA-0 --mode 1920x1200
--pos 1920x0
# => Run this script ( uses display to view some images)
# on the left screen: use right click on images to choose "next"
# Result: some images with overwrite the other screen
# X might crash
# ( remote ssh to system might still be possible to recover)
# - Sometimes it doesn't crash. E.g. second log in after a crash.
# - A try on a 1680x1050 dual head configuration gave no crash.

Actual Results:
X-server crashes. No keyboard action is possible (except Sysrq). Remote
login (ssh) is possible.
Program received signal SIGABRT, Aborted.
