[Solved] Firefox 3 crash - is it a bug?

[FishB8]

I am having a problem with Firefox 3 crashing. I did a backtrace and the segfault is taking place with libpixman. However I'm not sure if this is an actual bug, or perhaps something to do with my system.

I found a way to reliably reproduce it. If some people could do the following I'll be able to know if this is an actual bug or not. My packages are pretty up-to-date.

1) Install the Mostly Crystal theme for firefox (I doesn't do it reliably with the default theme) http://www.tom-cat.com/mozilla/
2) With the theme active, open Firefox
3) Press Alt-T to create a second tab
4) Try to drag one of the tabs to change the tab order
5) Firefox immediately crashes here for me, backtrace to pixman_fill in /usr/lib/libpixman-1.so.0

Thanks

*edit* forgot to mention my build options for firefox: USE="dbus gnome ipv6 mozdevelop xulrunner -bindist -iceweasel -java -restrict-javascript -startup-notification"

I cannot reproduce this error with:

www-client/mozilla-firefox-3.0-r1 USE="dbus ipv6 java linguas_pl mozdevelop startup-notification xulrunner"

(I'm not using gnome integration)

Maybe this is a problem with theme itself in certain configurations (I have x11-libs/pixman-0.10.0)?

Thanks smerf. Believe it or not, your post actually helped solve my problem. When you said you had pixman-0.10.0 installed, I realized that I hadn't bothered to do an equery to see which package it came from. I had just assumed that it came from the libpixman ebuild rather than the pixman ebuild.

I had already tried rebuilding libpixman before I posted to be sure it wasn't my build options. Obviously it had no effect. But when I rebuilt pixman with -ftree-vectorize turned off it fixed my problem.

Thanks.

Please file a bug report describing the problem and requesting that the flag be filtered out in the ebuild. Doing so, while retaining the current general structure of the ebuild, would require modifying x-modular.eclass to allow for it to filter CFLAGS.
