Yes sure. And that segfault happened with the *non*-problematic libxml2 
version. I should have been a little more clear: my whole point there 
was that *another* change than the one in libxml2 might have introduced 
a problem, which is just exhibited by the new libxml2. As we don't know 
whether it's libxml2's fault or the fault of another library, I have to 
mention every other breakage, too.

Now you may be right and it's not "related" to libxml2 in the sense that 
libxml2 might not be at fault for those issues, *but* those segfaults 
might be very well related in the sense that they might lead us to the 
very same cause leading to the segfaults we see inside libxml2. So your 
conclusion to not further look at those crashes can't be definitive 
(with our current knowledge).

Christian.
