Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

First of all, could we get output of the command

	rpm -qa *xulrun* *firefox* *mozilla* *flash* *plugin*

Please also install firefox-debuginfo (debuginfo-install is from
yum-utils package).

	debuginfo-install firefox

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.

Hi Matej,Since firefox will not only crash and it will logout the X system, how could i get the backtrace?

--- Additional comment from mcepl on 2008-09-23 08:43:45 EDT ---

so, when you are trying that running of firefox in gdb (you can redirect its stdout and stderr to the logfile for an additional security) there are no messages anywhere? I mean, when you try

gdb /usr/bin/firefox 2>&1 |tee firefox-log.txt

(and then you do what described above), the file firefox-log.txt is empty?

The log is not empty but it will still cannot catch the backtrace.Following is the content of log:

------------------------------------------------------------

Moreover,when i login via vnc(both from my laptop and from the debugging machine) and launch firefox to open that URL, it will NOT crash and X server will not down. And, when i open the URL with opera on debugging machine,it will not crash or down the X server also.

--- Additional comment from mcepl on 2008-09-24 06:31:30 EDT ---

Please attach your X server config file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below.

Could you please also try to run without any /etc/X11/xorg.conf whatsoever and let X11 autodetect your display and video card? Attach to this bug /var/log/Xorg.0.log from this attempt as well, please.

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

Thanks in advance.
