Comment 57 for bug 71913

A very similar bug and stack trace starting at:

   /usr/bin/Xorg(FontFileCompleteXLFD ...)

and causing firefox to crash Xorg (both nvidia and intel drivers) with SEGV in a reproducible way on certain web pages.

Appears on this RedHat bugzilla:

   https://bugzilla.redhat.com/show_bug.cgi?id=498500

It suggest a workaround as follows:
--------------------------------------------
1) edit /etc/X11/xorg.conf

2) Add the following line to "Section "Device":
      Option "XaaNoOffscreenPixmaps"

3) restart Xorg

I'm not seeing this bug on Ubuntu (I was seeing it consistently and frequently on RHEL5, on different hardware though)

Just thought it may be helpful to mention it here.
