That prelink patch is very, very unlikely to cause the issue.  It was 
also the only change between 2.13-3 and 2.13-4...  As I pointed out, 
there are other distros using that patch without reported issue and it 
is now in glibc mainline so nothing is obviously wrong with it.  Also, I 
have had no other crash reports since this update...


I just looked back through this thread and your backtraces are all over 
the place.  First it was an issue with libxcb, and then on a different 
VM it is somewhere completely different.    What is difference across 
your VMs that you get consistent crashes in one but not the other?
