Zelda Skyward Sword glitch with the beetle item (game freezes)

I have found this glitch while my walkthrough the sandship dungeon. I recorded the video afterwards, when i have finished the dungeon. In both cases will work, so you can test it anytime for yourself. Right behind you is a saving-statue so you've got nothing to loose... if you save. But you have to restart you wii after the game freezes anyway.
