Updated: XFree86-xserv-4.3.0-31

Andrew,

Yup, this happens when you are using -query and there are no entries in 
your .Xauthority file.  You can alleviate this by running it again after 
it crashes, since the previous entries are left in the file.  This is 
something that still has to be fixed or worked around and that is why 
these are 'test' releases.  Sorry for not describing this particular 
failure mode in the announcement.
