Description of problem: The subject URL crashes Firefox 2.0.0.9 causes FF to exit when the play button is clicked. This has occurred with other sites as well but not all embedded flash media. Workaround: Replacing FF with the pre-compiled Mozilla distributed version corrects the problem. I also re-spun the RPM with 2.0.0.10 source code (which requires changing two of the patches). Using this RE-introduces the issue.
Scratch that. Using the mozilla tarball only fixed one site. Removing libflashsupport stops the crash BUT now I have no sound. This was never a problem previously (FC7)
OK, pushing to correct component.
Why is this severity "Low"? As flash video is very common these days and the difference between the stability with Fedora 7 vs. 8 is huge, these videos (e.g. on spiegel-online.de, but also elsewhere) continue to crash gecko in an alarming rate. The OP ist right in that there are sites more error prone than others, but even the "better" sites will make gecko crash sometimes.
It's a pulse audio problem and a simple work-around. rpm -e alsa-plugins-pulseaudio libflashsupport kde-settings-pulseaudio I find that I am getting better audio without pulse. With pulse, I experienced a delay on playing system notifications (which might be more pronounced with KDE than Gnome or XFCE).
I assume that uninstalling pulseaudio will not restore the previous dmix functionality out of the box... so it isn't a viable solution for the "normal" user. As pulse seems to be going to be the desktop linux audio standard, I would rather prefer having those bugs fixed instead of just removing it...
install nspluginwrapper and ff will stop crashing. flash may go grey from time to time, just reload the page.
My mistake, should have asked about nspluginwrapper myself. I am sorry. Closing as NOTABUG
