Version details: Debian/sid
Distribution/Version: Debian/sid

Hi,

I got a private mail report of a crash with an ASF of which the file:
http://joule.via.ecp.fr/~lool/debian/foo.asf

is an extract.

I can reproduce the crash with gst-plugins 0.8.7 and 0.8.8 in Debian sarge and
sid.  Somehow, on my sid system, it doesn't occur.

Here are some bits of a backtrace:
Program received signal SIGFPE, Arithmetic exception.

It's painful to get plugins built with debugging symbols with the Debian
packages, so I did not install all debugging modules, I think the relevant part
is shown.

I don't know when I'll be able to look deeper into this.
