Bug Description

Description: firefox segmentation fault/crash when opening website

I tried the following steps several times, and it crashes after step 2) or after
step 3). Sometimes it doesn't crash (probality 1/2 is seems), I don't really
understand...

1) open mozilla-firefox
2) go to http://info.club-corsica.com/index.php?art=67onfray001
3) click on the link named "réagissez à cet article" (the first link just below
the text). The corresponding URL is
http://info.club-corsica.com/index.php?rub=message&idc=

(please pay attention to the contents of the website, I think what is written on
it is really dumb, but it is not the question (^_^))

I launched it from a concole. Here is the output that I get (crashes after
step.3). I think that it isn't very helpful, so if you can tell me how to make
it more verbose... :)

Of course I meant "don't pay attention"...

It works for me. But that web page contains a flash ad (middle top of the
screen). I just wonder if that page crashes or not depending of which ad you
are getting; it my case it was always the same one this morning: an ad for the
site www.corse.fr which worked fine on my machine.

And maybe the crashes are triggered by that ad when trying to produce a sound on
your machine (notice the "open dsp: No such file or directory" errors in your
report; that's sound related). Do you have a flash plugin installed in your
firefox? Can you crash on that web site with your plugins disabled or if that
ad is blocked before being displayed? (in my case this blocked the ad:
http://www.mozilla.org/support/firefox/adblock)

You must be right. Today I tried the same website more than 10 times, and it
didn't crash (with or without flashplayer). So I guess that it was because of a
specific ad that is not here today...

By the way, the version of flashplayer that I use is 7.0.25-0.0 from multiverse
(not the 7.0.25-woody0.0 from marillat).

If there is nothing more that we can do, I guess that we can close the bug and I
will reopen it if I come accross the same kind of problem, this time paying
attention to plugins :)...
