I believe this is the bug Paulo already submitted a patch to fix over the weekend: http://patchwork.freedesktop.org/patch/7998/ Still no commit AFAIK. (In reply to comment #2) > Still no commit AFAIK. Yes. If you could test the patch and reply to the email with a tag "Tested-by: David Ronis <david.ronis@yourdomain.com>" it may accelerate the process. Mentioning this bug report might make things even faster. Unfortunately in our current development process it is a little bit hard to get patches committed to the master branch, so even trivial bug fixes like this require a lot of persistence. Here is the latest patch version: http://lists.x.org/archives/xorg-devel/2011-November/027213.html http://patchwork.freedesktop.org/patch/8008/ Tested-by: David Ronis <david.ronis@mcgill.ca> The patch works.

I follow the git/master on an HP Pavillion laptop, currently running a 3.1.2 kernel on what is basically a current slackware distibution. The laptop has an ati-radian card (R200). I built with debugging symbols and ran 'gdb X' as root; here's the backtrace: Program received signal SIGSEGV, Segmentation fault. 0x080f4d86 in OpenConfigDir (path=0x81fef08 "%A,%R,/etc/X11/%R,%C/X11/%R,/etc/X11/%X,%C/X11/%X", cmdline=0x0, projroot=0x81feff0 "/usr", confname=0x820a30a "xorg.conf.d") at scan.c:861 861 free(list[num]); [according to gdb num=-2 and list is 0x0] (gdb) thread apply all bt full Thread 1 (Thread 0xb745f7e0 (LWP 30196)): #0 0x080f4d86 in OpenConfigDir (path=0x81fef08 "%A,%R,/etc/X11/%R,%C/X11/%R,/etc/X11/%X,%C/X11/%X", cmdline=0x0, projroot=0x81feff0 "/usr", confname=0x820a30a "xorg.conf.d") at scan.c:861 list = 0x0 num = -2 dirpath = 0x0 pathcopy = 0x8918fe0 "%A" template = 0x8919008 "%C/X11/%X" found = 0 cmdlineUsed = 0 #1 0x080f4f2e in xf86openConfigDirFiles (path=0x81fef08 "%A,%R,/etc/X11/%R,%C/X11/%R,/etc/X11/%X,%C/X11/%X", cmdline=0x0, projroot=0x81feff0 "/usr") at scan.c:956 No locals. #2 0x080ba63a in xf86HandleConfigFile (autoconfig=0) at xf86Config.c:2328 filename = 0xbfa9767c "\360<\221\b\300\031\\\267\320\003&\b\250v\251\277\370\376\t\b\f\301&\b@" dirname = 0x81ffc16 "Log file: \"%s\", Time: %s" sysdirname = 0x8919d70 "/usr/share/X11/xorg.conf.d" filesearch = 0x81fee74 "%A,%R,/etc/X11/%R,%P/etc/X11/%R,%E,%F,/etc/X11/%F,%P/etc/X11/%F,/etc/X11/%X,/etc/%X,%P/etc/X11/ %X.%H,%P/etc/X11/%X,%P/lib/X11/%X.%H,%P/lib/X11/%X" dirsearch = 0x81fef08 "%A,%R,/etc/X11/%R,%C/X11/%R,/etc/X11/%X,%C/X11/%X" filefrom = X_DEFAULT dirfrom = X_DEFAULT scanptr = 0xb759f5a0 "%.3s %.3s%3d %.2d:%.2d:%.2d %d\n" singlecard = 0 implicit_layout = 0 #3 0x080c2b09 in InitOutput (pScreenInfo=0x8272ca0, argc=1, argv=0xbfa97804) at xf86Init.c:365 i = 0 j = 0 k = 136709072 scr_index = -1219665935 was_blocked = 0 modulelist = 0x0 optionlist = 0xb77e1820 screenpix24 = 134735405 pix24 = 3215554328 pix24From = X_DEFAULT pix24Fail = 0 autoconfig = 0 configured_device = 0xb78c4ab8 #4 0x080631bc in main (argc=1, argv=0xbfa97804, envp=0xbfa9780c) at main.c:204 i = 256 alwaysCheckForInput = {0, 1}
