title: 4.1 android emulator not detecting sd card
body: <p>I used to use a 4.1 kitkat x86 android emulator with an sd card for testing. After upgrading Android Studio to 2.3, i'm no longer able to access the supplied sdcard in android making testing impossible for me.
  Google hasn't had answers for this and i also fail to see any clues in the emulator or adb logs. The avd has been recreated new, (i deleted the old avd folder to prevent goop from fouling things up). It simply doesn't work anymore.</p>
  
  <p>Here's the output when starting the emulator on Kubuntu 14.04 amd64</p>
