Apps using QCamera crash when sandboxed on Mac OS X

System: Mac OS X 10.8.5, Qt 5.2.1

Compile the camera example the comes with Qt source. Sandboxing it by creating a self-signed certificate (call it "SandBoxTest", for example), run these commands in console:

macdeployqt camera.app
codesign -f --entitlements entitlements.plist -s "SandBoxTest" camera.app

Run camera.app, it crashes.

The content of entitlements.plist is the following:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
