When using ACTION_VIDEO_CAPTURE, thumbnail is either non-existent or not accessible

[GoogleCodeExporter]

What steps will reproduce the problem?
1.
        Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
        startActivityForResult(intent, REQUEST_CODE);
2.     in onActivityResult(), attempt to retrieve the video and thumbnail.
example code:

        final String filePath = data.getStringExtra(CameraManager.EXTRA_VIDEO_FILE_PATH);
        final String screenshotPath = data.getStringExtra(CameraManager.EXTRA_THUMBNAIL_FILE_PATH);
        Log.d(TAG, "Camera video location : " + filePath);
        Log.d(TAG, "Camera screenshot location : " + screenshotPath);

        File screenshot = new File(screenshotPath);
        if (screenshot.exists()) {
            doStuff(filePath, screenshotPath);
        } else {
            Log.d(TAG, "Waiting for file to be written.");
            // wait for file to be written, then do stuff
            fileObs = new FileObserver(screenshot.getParentFile().getAbsolutePath(),
                    FileObserver.CLOSE_WRITE) {
                @Override
                public void onEvent(int event, String path) {
                    doStuff(filePath, screenshotPath);
                }
            };
            fileObs.startWatching();
        }
    }

What is the expected output? What do you see instead?
expected output is for both files to exist or eventually exist.

fileObs never observes a CLOSE_WRITE on the thumbnail file.

What version of the product are you using? On what operating system?
XE12

Please provide any additional information below.

log example output:
Camera video location : /mnt/sdcard/DCIM/Camera/20131226_151859_219.mp4
Camera screenshot location : /data/private-cache/t_thumb_20131226_151859_219.mp4

The symptoms are identical to 
https://code.google.com/p/google-glass-api/issues/detail?id=355 (which is not 
fixed - only a workaround was suggested)

No, this is not the same issue as #355, I'm not attempting to set an output 
location, just monitoring the output location I was told (in the resulting 
data) would exist.

I was not referring to the declared problem, but the stacktrace I got. It is 
also about thumbnails. Not only is it about thumbnails, but it is also 
complaining that thumbnail could not be created. This seems quite relevant to 
your problem, imo

This has been fixed as of XE16.
