crash on coming back to full screen view via recent task button

[GoogleCodeExporter]

What steps will reproduce the problem?
1. open a video in fullscreen using the sample app project (activity 
TestHTML5WebView)
2. click on play
3. click on the android device home button
4. go back to the app using the recent task android device button

What is the expected output? What do you see instead?
I would expect to see the video screen again.
Instead i get an application crash with this in logcat:
