CameraRoll crash silently after calling facebook-ANE (Android)

Hi,
I'm using AIR 19 (and tested with 20) with facebook ANE (free version to download).
When I launch firstly the ANE to login or share content to Facebook, everything works correcly, but after this if I launch CameraRoll.browseForImage(), the CameraRoll class stop responding (crash silently and return to the app to continue working. No error, select or cancel event dispatched).

If I launch CameraRoll one more time I have an error message, because one instance of CameraRoll continue open.
If I launch the CameraRoll befor login with ANE, everything works correctly.

This problem occurs on Android, but not on IOS!

The team who builded the ANE, have no idea about this problem because they doesn't know if CameraRoll on Android use/dispatch/listen to specific event or something other.

import flash.media.CameraRoll;

FB.getInstance(FB_APP_ID_NUMBER);
FB.logManager.addEventListener(FBEvent.LOGIN_DONE, fbGetPermissionPublishSuccess);
FB.logManager.addEventListener(FBEvent.LOGIN_CANCELED, fbGetPermissionCanceled);
FB.logManager.addEventListener(FBEvent.LOGIN_ERROR, fbGetPermissionError);
FB.logManager.requestPermission(LogManager.WITH_PUBLISH_PERMISSIONS, Permissions.publish_actions);

private function fbGetPermissionPublishSuccess(event:FBEvent):void {
if (CameraRoll.supportsBrowseForImage) {
  camera = new CameraRoll();
  camera.addEventListener(MediaEvent.SELECT, mediaEventComplete);
  camera.addEventListener(Event.CANCEL, browseCancelled);
  camera.addEventListener(ErrorEvent.ERROR, mediaErrorHandler);
  // Open up the camera roll
  camera.browseForImage();
  }
}

Any idea about this?
Thanks in advance.
