[webkit-help] debugging webkit on 64bit ubuntu 11.10

[sachin nikam]

I have successfully built revision 102608 and i am running the test
browser successfully.
However, I have not been able to hit any breakpoints within webkit
code, when I attach to the process "GtkLauncher".
I found this thread to be relevant
https://lists.webkit.org/pipermail/webkit-help/2011-October.txt
but I dont find any "webProcess" running on my box.
Is there a different process that I need to attach on ubuntu?
