Took me a while, but I was able to reproduce the problem and take a complete
log.

No wonder that it crashes, what flash does here is destroying the device fi=
rst
and then trying to destroy the decoder who depends on the device:

vdp_device_destroy(1)
vdp_decoder_destroy(2)

Sounds like a bug in flash to me, but on the other hand the VDPAU state tra=
cker
shouldn't crash, but just return an error here.

Going to take a look into the code if we can't fix that somehow.
