[SOLVED] Firefox 4.0.1-1 Segmentation fault

As the title sugguests, I have no idea what really is going on with firefox. I'm providing as much info as I can below.

I hadn't updated my system for several weeks, and I did an system update yesterday which updated firefox to 4.0.1-1 from 4.0-1.
Now I'm getting this weird behavior from firefox: some sites, e.g. www.archlinux.org, will not segfault firefox (I'm posting this in firefox), while many others, e.g. www.ubuntu.org will segfault firefox without any error message other than "Segmentation fault". The "about:addons" page segfaults firefox too.

Things I've tried that didn't work:

• Make sure the system is up to date by running `pacman -Syyu` against an updated mirror.

• Start firefox with no ~/.mozilla at all. Also passing the -safe-mode flag.

• Add a new user and start firefox from this user's X session.

• Reboot after `touch /forcefsck`.

Additional info:

• The last 50 lines of output from `strace firefox` is here: http://dpaste.com/539995/ (Segfaults on me!)

• An unusual thing I did to my computer yesterday, is setting the system time to UTC and adjust the BIOS time accordingly. This made the hardware clock go back several hours.

• Window Manager: dwm 5.8.2 with custom patches. I also rebuilt dwm, just in case.

Edit:
Downgrading dconf from 0.7.4-1 to 0.7.3-2 fixes the issue.

pacman -U http://arm.konnichi.com/extra/os/$(arch)/dconf-0.7.3-2-$(arch).pkg.tar.xz

See also FS #24160

Edit:
dconf 0.7.4-2 fixes this issue. wonder is wonderful.

Re: [SOLVED] Firefox 4.0.1-1 Segmentation fault

I had actually the same problem since yesteday evening. 
Reverting from dconf  0.7.4-1 back to 0.7.3-2 solved the problem.  I suppose it is the same problem as https://bugs.archlinux.org/task/24160?p … &sort=desc

Downgrading dconf seems to have solved this. Thanks!

Thanks, that did it.

Hm, but that bug report's most recent comments claim the bug was fixed with dconf 0.7.4-2, but I experienced the Firefox crash after already having upgraded to dconf 0.7.4-2.

I had to downgrade to 0.7.3-2 as you suggested.
