[Feisty AMD64]Closing tab in Firefox kills xorg

[der_vegi]

this is kind of strange: sometimes when i close a tab by hitting strg + w in firefox, the x-server restarts, i have to log in again.
unfortunately, i cannot alway reproduce the bug, it has happened several times on http://direct2dell.com/one2one/default.aspx and one times on www.seb.de. when firefox crashed on the dell site, i logged in again, restored the session, closed the tab and ended up with a restart of x again.

i'm using feisty final on an amd64 machine.

maybe the log file helps?

Hmm, there isn't an obvious error message in the Xorg.0.log file.

Can you run `strace firefox` in a console, run it until it crashes, and then attach the last 100 lines or so here?

Also, please tell what version of firefox you're using.

Fwiw, I've had firefox crash while using dell's website, but not Xorg. Have you looked in the firefox bug tracker to see if this is a known issue for them?

[Bryce Harrington (bryce)]

Is this still a problem? If so, if you could answer at least some of the above questions it may help. Note that after the crash, the error might be in your Xorg.0.log.old file, so if you could, please check and upload that.

Okay, this doesn't happen anymore. I'm using the latest firefox from the repos Mozilla/5.0 (X11; U; Linux x86_64; de-de; rv:1.8.1.4) Gecko/20061201 Firefox/2.0.0.4 (Ubuntu-feisty).

Thanks for confirming the issue no longer occurs. Closing as fixed. If you do spot it again though, please reopen.

another webpage, similar problem

[der_vegi (m-may)]

okay, it happened again. now by browsing the site www.atomausstieg-selber-machen.de and opening all the news articles between july 20th and july 24th in new tabs. i open these tabs and while loading them, xorg crashes.

[der_vegi (m-may)]

hmpf. i've run firefox with strace several times, but where does the output go? now running strace with the -o option, but now i can't reproduce the crash anymore...

[der_vegi (m-may)]

ah, finally. here the output of strace firefox.

Hi der_vegi,

Unfortunately this still isn't providing an error message, which will make it difficult to troubleshoot.
Can you please follow the steps at https://wiki.ubuntu.com/DebuggingXorg to obtain a backtrace of xorg?

Also, please attach the output of lspci -vnn, and a copy of your /etc/X11/xorg.conf.

Can't reproduce this bug anymore on Feisty with all the latest updates till sep. 25th.
