Comment 4 for bug 995918

I found that tumblerd has this issue when it finds no codec for the video. It has nothing to do with the container format but with the contained video codec. I have some files which contain wmv3 and they cannot be played by Totem. Exactly these files cause tumblerd to not close them, so external media cannot be unmounted.

Is there a way to prevent tumblerd from scanning external media?
