I've witnessed the same problem. I managed to get a backtrace over ssh
and attching GDB to the X process and then trying to watch a video with
totem. I've also witnessed the same to happen with mplayer and vlc.
Probably something to do with hardware accelerated video playback or
scaling or something.
Anyway, it seems that the problem is in the proprieaty AMD video driver.
Program received signal SIGSEGV, Segmentation fault.

I tried to use gdb generate-core-file but the machine ended up dead
locked. I could try again with serial console + crashkernel if that's
any use, but as it's proprietary driver, I doubt it would be.
