[webkit-qt] [QtTestBrowser Hangs always]: Similar issue as https://bugs.webkit.org/show_bug.cgi?id=79785 in UBUNTU 11.04

[santosh mahto]

Hi all

I am facing the issue same as
https://bugs.webkit.org/show_bug.cgi?id=79785in Qt webkit build  with
UBUNTU not mac.

ISSUE: on launching QtTestBrowser .. it gets hanged , probably due to lock
deadlock

I am trying to build webkit2 latest code with latest Qt5 git cloned build.

Other configuration : Ubuntu 11.04 , glibc :2.3.2

The call stack for hangs are
