reproducible browser crash in linux

Both mozilla 1.7.5 and firefox 1.0 on linux reproducibly crash when accessing
this url:

http://www.offroad-challenge.home.ro

A backtrace seems to indicate that the flash player is at fault.
Shockwave Flash 6.0 r79

Program received signal SIGFPE, Arithmetic exception.

The backtrace is from firefox.

Kernel is 2.6.7, sound is ALSA + OSS emulation. Even if I start ESD, the
result is the same (it crashes at the same location with the same floating
point exception).

Unfortunatelly, I've not found a more proper method to report this, other than
this forum.

Anyone having the same problem ?

Thanks,

Matei
