Need to add that most of the time it happens when submitting stuff to Sales
Force (heavy need of JavaScript), and it did not happen with previous release
(1.5.0.12-7).

Another correction, version which is failing is firefox-1.5.0.12-9.el5

Marek, I need your help, either go with the following procedure for getting
useful backtraces, or at least give us exact version of the package this crash
happens? Is it firefox-1.5.0.12-9.el5 all the time? Which architecture? I need
to know which exact package is causing this problem, otherwise I am not able to
get any useful information from the core dumps.

The standard blurb about -debuginfo follows:

Please install firefox-debuginfo; in order to do this you have to enable
-debuginfo repository.

	yum install --enablerepo=\*debuginfo firefox-debuginfo

(if you use x86_64 firefox, install firefox-debuginfo.x86_64  package).

Then run firefox with a parameter -g. That will start firefox running inside of
gdb debugger. Then use command run and do whatever you did to make firefox
crash. When it happens, you should go back to the gdb and run

	(gdb) thread apply all backtrace

This produces usually many screens of the text. Copy all of them into a text
editor and attach the file to the bug as an uncompressed attachment.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

I have the above strace log, will that help or you still want me to run the gdb

The strace is useless in case of SIGSEGV, my core dump are from
firefox-1.5.0.12-7.el5 as I mentioned in my first comment, in second one, I've
attached list of all packages (gtk..). I was not able to get a backtrace as the
user is quite busy and doesn't want to troubleshoot it with me via vnc.

Created attachment 294660 [details]
list of all installed packages

Here is what i got from the user whose firefox was crashing everytime he tried
to open gtk-file-selector (save as, browse, print, etc.)

I hope it helps. Let me know if you need anything else.

What else do you need for debugging?

Obtained gdb backtrace from other core dump files
core.3798, core.3896,  core.4046

It is a little different from other backtraces which were attached earlier.
Thought it will be usefull.

Firefox just crashed again.  Here's what I have installed:
nss-3.11.7-1.3.el5
nspr-4.6.5-3.el5
firefox-1.5.0.12-11.el5_1

Should I be running the updated nss nspr from above if I want to help test this fix?

Help Desk has been deploying the latest brew packages
(http://brewweb.devel.redhat.com/brew/buildinfo?buildID=69239), and we have had
a lot of success.  We are still not 100% rid of our crashes, but we are back to
a stability level that we had prior to 5.1 rolling out and all hell breaking loose!

An advisory has been issued which should help the problem
described in this bug report. This report is therefore being
closed with a resolution of ERRATA. For more information
on the solution and/or where to find the updated files,
please follow the link below. You may reopen this bug report
if the solution does not work for you.

firefox still crashes on me at least once daily with the latest build.  Is there
another bz tracking the latest crashes?

Sorry if this sounds dumb, but https://rhn.redhat.com/errata/RHBA-2008-0147.html
says (in part):

  ..packages were linked against an incorrect version of a library which
  would cause Firefox to randomly crash while the browser was in use. 

but looking at the new srpm I can't see any change to the libraries that the
specfile specifies.

Would it be possible to explain which libraries were incorrectly being picked up
and perhaps what was changed to correct it?  Something in the brewbuilder setup
perhaps?

It's looking to us more and more like we have multiple issues here.  My question
to those still experiencing crashes with the latest firefox 1.5:  If you remove
all of your plugins do you still see instability?  We are pointing our fingers
at flash currently, but I don't have enough info yet to say that it is
definitely causing most of the issues that we are seeing.

Is there a possibility of a fix for this or will a newer release of FireFox be
offered in yum updates or the RHN Channel. It is very difficult to run my
workstation at work running a RHEL5.1 Server as my primary machine with the
browser crashing constantly.

Any updates or status would be greatly appreciated.

thanks

I removed all of my plugins and still get crashes.  I don't believe flash was
involved in my last crash.

I believe most, if not all of the crashes occur when opening a dialog box that
opens and external file, such as a pdf file.  Once the crash occurs, if I return
to the same site and open the file, the file opens fine.

I agree when you try to open a dialog box, for example when I was on RHN 
Network trying to upload a sosreport the browser crashes. I have to use 
Konqueror now, which does not have the functionality as FireFox has built in.

Yes, new crashes are tracked at bug 433823

Hi All. 
If this is related to the bug in Bug 430140 you might want to see the
thread at:

http://www.centos.org/modules/newbb/viewtopic.php?topic_id=11589&viewmode=flat&order=ASC&start=20

It seems to be mainly a gtk2 issue. Look around comment #30 onwards in that
thread. There are simple fixes there for this crash.

Will a patch be rolled out to correct this issue in RHEL5.1 Enterprise Server 
in the future to correct it without having to hack the system so to speak?
