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?
