Android error: java.lang.IllegalStateException: trying to requery an already closed cursor

Question

environment (Linux/Eclipse Dev for Xoom Tablet running HoneyComb 3.0.1)

In my app I'm using the camera (startIntentForResult()) to take a picture. After the picture is taken I get the onActivityResult() callback and am able to load a Bitmap using a Uri passed via the "take picture" intent. At that point my activity is resumed and I get an error trying to reload the images into a gallery:

The only cursor logic I'm using is that after the image is taken I convert the Uri to a file using the following logic

String [] projection = {
    MediaStore.Images.Media._ID, 
    MediaStore.Images.ImageColumns.ORIENTATION,
    MediaStore.Images.Media.DATA 
};

Cursor cursor = activity.managedQuery( 
        uri,
        projection,  // Which columns to return
        null,        // WHERE clause; which rows to return (all rows)
        null,        // WHERE clause selection arguments (none)
        null);       // Order-by clause (ascending by name)

int fileColumnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
if (cursor.moveToFirst()) {
    return new File(cursor.getString(fileColumnIndex));
}
return null;

Any ideas what I'm doing wrong?
