With futher investigation, I found out that other swfs work on latest version 1.5.8.0 too. I have attached them.
It means there is some problem with your source swf file and the one I used as a source earlier.
gif.swf
source.swf
Anyway, we will investigate it and fix it as soon as possible.
Many Thanks and Kind Regards,
