Hello!

I discovered this issue while browseing with WebKit based browser like Midori
or Epiphany within the new Gnome-Shell.

Steps to reproduce:
1. Gnome 3.2 with Gnome-Shell, using the Radeon-Drivers from Linux/XORG
1. # sysctl -w kernel.sysrq="1" // WARNING! This will not save your ass!!!
2. $ launch Midori or Epiphany with enabled JavaScript
3. http://piratpix.com/bpt2011.1/index.html // Pictures from federal convent of
german Pirate-Party, note: There is a "javascript void(0)" error on the site
4. open one or some image with the mouse

Results:
* Crash/Hang of system
* MagicSysRq will not help!

Software/Hardware:
pacman -Q libwebkit libwebkit3 midori epiphany
libwebkit 1.6.1-1
libwebkit3 1.6.1-1
midori 0.4.1-1
epiphany 3.2.0-1
and also:
* Self compiled vanilla kernel 3.0.3 and stock kernel 3.0.6 from Archlinux
* Graphis-Card is an AMD Radeon 5650, with open-source drivers

Not affected:
* Gnome 3.2 in Fallback-Mode
* Firefox 7 (shows also the javascript void(0) but displays everything like
usual)
* Fedora 15 with Radeon 4670 and open-source drivers and Midori 0.3.6

Soughts:
* Maybe row of problems start with the JavaScript-Error
* Next Step is WebKit
* Next Steop is Gnome-Shell
* But even if there bugs in all of them above, the operating-system should
crash/hang in any chase. So I afraid this is a bug in kernel/radeon-driver.
* It is also interesting the the Fedora 15 with an other AMD Graphics-Card is
not affected.

Thanks
