So i feel free to close it.

Apparently, this isn't entirely fixed. I have a bug report [1] in Gentoo for that, I'll tell the user to bring more info in here.

Thanks

(i'm the one reporting the pb on gentoo)

i keep on having this crash using xorg-server 1.7.1
Most of the time it happens when i select some text in kmail.

The last backtrace (today..) is slightly different:

I've experienced the bug with x11-drivers/xf86-video-ati-6.12.4 and the same driver from git repository (latest try : git version of november 21st)


I've never been able to reproduce the crash once i had applied the patch on:
http://lists.freedesktop.org/archives/xorg/2009-March/044396.html

This bug seems to be affecting a lot of people. Here are some links to distro bug reports since they have attached files with logs, backtraces, xorg.confs and lspcis:

https://qa.mandriva.com/show_bug.cgi?id=55673

http://bugs.gentoo.org/show_bug.cgi?id=288747

Yes. At least on gentoo, I know of several people that suffered from this bug and who now apply the patch (Gentoo does not apply the patch to its package, yet?)

I also occasionally experience this issue when opening the "new mail" window in KMail. My attempt to get a readable backtrace resulted in this (I used addr2line on a debug binary, not the one which actually crashed - but it looks right):

3: FindGlyphByHash
/build/buildd/xorg-server-1.6.4/obj-i486-linux-gnu/render/../../render/glyph.c:263
4: ProcRenderAddGlyphs
/build/buildd/xorg-server-1.6.4/obj-i486-linux-gnu/render/../../render/render.c:1131
5: ProcRenderDispatch

6: Dispatch
/build/buildd/xorg-server-1.6.4/obj-i486-linux-gnu/dix/../../dix/dispatch.c:457
7: main
/build/buildd/xorg-server-1.6.4/obj-i486-linux-gnu/dix/../../dix/main.c:399

This is with Kubuntu 9.10, X.Org X Server 1.6.4, NVidia binary drivers 185.18.36, KDE 4.3.5, KMail 1.12.4.

Fixed in 185185eeb44a277c324be0f58a4b4a469b56b69b, and nominated for backport.

Thank you very much :) . Now I pray that this patch makes it into the next *buntu.
