Steps to reproduce:
1. Open fennec on Android
2. Switch to another app and tap on a link
3. Choose to open the link in fennec

Expected results: Fennec reappears and the link opens in a new tab.

Results: Fennec reappears and the link opens in a new tab, *and* a small black rectangle appears in the top left corner of the screen.  The black rectangle remains fixed in the corner, obscuring whatever Fennec chrome or content is there.

I can't reproduce this by following similar steps in desktop Fennec.  It happens only when opening a link from another Android app while Fennec is already running.  Just opening a link in a new tab does not trigger the bug, nor does launching fennec by tapping a link from another app.

This bug occurs in Nightly 10.0a1 (I first noticed it in the 2011-10-14 build, but I don't know exactly which builds are affected).  It does not occur in Aurora 9.0a2.
This is due to the camera support added in bug 690635 for some devices.

Matt, you can assign it to me if you prefer.
Sure!  Thanks.

I was always able to reproduce this issue while I've performed the str from bug 696013

Fixed by adding the camera view only when we need it. It looks like it was popping on top of the gecko surfaceview each time fennec was paused/resumed (eg just choosing "browse" to get the filepicker chooser was enough to trigger the bug)

The code looks good.  Has it been tested to make sure it works on phones that were affected by bug 690635?
