Kindle Fire, Particle System

Unity 3.5.3f3 I create an empty scene with one main camera and default particle system object. Run it on my Kindle Fire. It works, but if I press Home button and then resume to my app then app crashes and restarts. On my Nexus S evrything works fine. Looks like it's Unity bug, but I'm not sure so could somebody check it please? And how can I fix it? Only thing I have found is that there're no bug if I disable Particle Renderer before goto home screen.
