Just crashed:

        Program received signal SIGQUIT, Quit.
        0x00007f46fcb33fd3 in __select_nocancel ()
            at ../sysdeps/unix/syscall-template.S:82

        Continuing.

        Program exited with code 01.

Sorry about the lack of symbols, but I just noticed that I missed gdb's
complaint about symbols mismatch (there were more, pasting only a few):

        warning: the debug information found in "/usr/lib/debug/usr/bin/Xorg" 
does not match "/usr/bin/Xorg" (CRC mismatch).
        warning: the debug information found in 
"/usr/lib/debug/usr/lib/xorg/modules/extensions/libextmod.so" does not  match 
"/usr/lib/xorg/modules/extensions/libextmod.so" (CRC mismatch).
        warning: the debug information found in 
"/usr/lib/debug/usr/lib/xorg/modules/extensions/libdbe.so" does not match 
"/usr/lib/xorg/modules/extensions/libdbe.so" (CRC mismatch).
        warning: the debug information found in 
"/usr/lib/debug/usr/lib/xorg/modules/extensions/libglx.so" does not match 
"/usr/lib/xorg/modules/extensions/libglx.so" (CRC mismatch).

I got the symbols from the repository yesterday, packages
xserver-xorg-core-dbg, libgl1-mesa-dri-dbg, and xserver-xorg-video-intel-dbg.

Thanks,
                Alberto
