 From the way you've described it, it sounds like you've uncovered a bug 
in an old version of libx11. If this is the case, then why does Debian 
need stronger versioned dependencies between the server and this lib? 
That's not a versioning issue after all, that's just a normal bug. The X 
server doesn't actually require the newer library version.
