There was at least one other size_t/socklen_t initialization issue  
(see [1]) that got fixed with a commit on Wednesday [2].

So, you may actually experience other unitialized memory issues with  
nx-libs 3.5.0.24.

Please use nx-libs from the nightly builds (or build it your self) and  
re-test with my fixes for the xtrans code in NX/X11. (xtrans is  
responsible to set up listening sockets for the X-Server as well as  
handle incoming connections).

Another issue may well be: does your Fedora PPC64 system use  
poly-instatiated /tmp directories? If so, then you want 3.5.0.25, as  
well.
