For the record:

I've helped debug someone's segfaulting xsltproc over the past few weeks, 
and we've found the cause of the segfaults now. The user had the following 
line in /usr/pkg/share/xml/catalog:

        <nextCatalog catalog="/usr/pkg/share/xml/catalog" />

With the file loading itself again and again, the resulting segfault 
(probably due to some stack overflow) is no big surprise.

I'm not sure (yet...) where that line comes from, but if you see your 
system behave in a similar way, that's where you can start looking.
