Tijl,

Thanks for responding. 

Strange things happen... I did the following:

(1) I re-compiled gstreamer1-libav *with* debug symbols. 
(2) Started Firefox, went to youtube and played a HTML5 video. It played 
    fine. Firefox did not crash.
(3) I re-compiled gstreamer1-libav *without* debug symbols.
(4) I repeated step #2. Firefox crashed at the same location as before.
(5) Repeated step #3. No crash. Strange...

The processor type is:

  CPU: Intel(R) Core(TM)2 CPU         T5600  @ 1.83GHz (1828.80-MHz 686-class CPU)
    Origin = "GenuineIntel"  Id = 0x6f6  Family = 0x6  Model = 0xf Stepping = 6

Full dmesg output is at: 

  http://www.eskimo.com/~joji/dmesg.txt


Looks like there is a bug in gstreamer1-libav. Just don't know how to
find it if it doesn't show up when debug symbols included..

Suggestions?
