qtwebkit-examples-and-demos/browser/browser not responding

I'm building QT5 for ARMV7/directfb platform.

Running the following command line:
$QT-PATH/examples/qtwebkit-examples-and-demos/browser/browser -platform directfb http://www.google.com

I'm able to go throw the menu only for the first time.

The browser is no more responding.

When I attach the process to gdb, I have the following back trace:

I observed the same issue when building QT-5 for x86/directfb.
