How did you get that? Just trying to play the file?

And a stack trace would be nice.

------- Comment #4 from pekka.lampila at iki.fi  2007-12-17 08:51 PST -------
I couldn't reproduce this crash. Tried with git and 0.5.4 versions

What swfdec and Firefox versions are you using?

To get a backtrace try:
firefox -g http://www.konar.ict.pwr.wroc.pl/zawody/flash.html
then after it crashes you can do:
bt full
and post the output here

Thank you.

My versions are 0.5.4 and 2.0.0.10:

zajec at acer:~> rpm -qa | grep 'swfdec'
libswfdec-gtk2-devel-0.5.4-0.pm.2

MozillaFirefox-2.0.0.10-0.1
zajec at acer:~> firefox --version

Unfortunately I can not use "bt" or "backtrace" tools. Both
commands are
unavailable in my openSUSE 10.3. I also couldn't find RPM caller
"bt" or
"backtrace".

I found some help for Ubuntu: https://wiki.ubuntu.com/Backtrace but all I get
is this error:

------- Comment #6 from pekka.lampila at iki.fi  2007-12-17 11:28 PST -------
Thank you for the information.

I'm sorry my explanation about getting a backtrace was bad. Firefox is
somewhat
special, so the Ubuntu HOWTO doesn't work directly. But if you use
"firefox -g
2>&1 | tee gdb-firefox.txt" instead of "gdb firefox 2>&1
| tee gdb-firefox.txt"
it should work correctly. Just remember to shutdown all Firefox windows before
doing this.

Debug of crash (I hope it is)

What I did:
1) Closed Firefox and made sure there is not firefox process in system
2) Used firefox -g 2>&1 | tee gdb-firefox.txt
3) Entered http://www.konar.ict.pwr.wroc.pl/zawody/flash.html and activated
animation
4) Saw Firefox crashing ;)

Thanks for explaining and being patient, I don't really know much about
debugging :) I provided gdb-firefox.txt, if anything else is needed, just let
me know.
