title: Unfortunately System UI has stopped
body: <p>I gets this message every time I start 4.0.3 emulator in WXGA800 mode. My app works fine without running System UI except action bar does not appears and I can't test my actionbar functionality. 
  My OS is Win7 x64. Sdk revision 19.
  Any ideas?

  <p>I figured it out. It happens when hw.mainKeys set to false in AVD setings. Thanks for your answers!</p>
