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.
