nautilus crashes while trying to show swf file properties

I can provide this swf file if you need it

Thank you for your bug. What version of Ubuntu do you use? What do you call "crushes"? crashes? having an example attached to the bug would be useful

Edgy eft.

Well, crushes. No icons on desktop for some seconds, then nautils restarts.

Here is the swf file. It should be flash 6.

Thank you for the example, it makes the totem thumbnailer crash on feisty to libswfdec code:

On post-0.5.3 (git current), it doesn't crash anymore, it just displays nothing
(which is an improvement)
