Client Error when using tail:core + mdg:camera

[Rebolon]

Hi,
this night i've seen that if i use your package with mdg:camera, i have javascript error when i click on "use photo" : Uncaught Error: Must be attached

To reproduce this just : add mdg:camera and tail:core
Then use mdg:camera sample to allow user to take a photo.
Then open the browser to localhost and click on the button to take a picture
Finally click on "Use photo"

In the console you can see the Error.

Without tail:core it works well.
Hope it helps
