webkit://gpu output (working)

I am finding the following broken:

* Navigating to 'webkit://gpu' results in a segmentation fault (epiphany and MiniBrowser);
* The tanks demo (http://webassembly.org.cn/demo/Tanks/) displays 'Your browser does not support WebGL'.

Reverting the patch from Bug 235946 restores normal functionality.  (I should also add, I had previously reverted the changes from Bug 236290 with no effect, so both patches were reverted in my now working build.)

It was still breaking as of the most recent build I did, which was at svn rev 289465.



Segmentation fault looks like this:

Thread 2 received signal SIGSEGV, Segmentation fault.

I have attached the output of the working 'webkit://gpu'.

Thanks!
