Interesting...I'm back at my Mac in my office today, and, while I see the same error with my Mac, it is less frequent than with my Linux system (successfully connects more often).  However, this isn't a great test, since I was operating over a VPN with the Linux client, anyway, so there are some other variables there.

Still, I am puzzled by the fact that I can successfully connect and start an xterm (every time) and then run "startxfce4" and have it work, no crashes or errors, every single time.  Maybe this somehow works around the bug/segfault in NXPlayer, and perhaps this display segfault works equally well on both Linux and OS X.  I'll have to try out NX Player on Windows along with going back to some of the older clients and the OpenNX client for Mac to see what I can get to work/break.

Also, regarding the suspend/resume behavior (which also points to a client-side issue), I concur that the suspend actually seems to work fine on the server-side, and, eventually I can reconnect, but, again, it's a sort of hit-or-miss thing that fails with the same error.

As far as the bug you reference for the _XGetRequest issue, this has been fixed in the openSuSE repositories for FreeNX/NX - I believe nxagent-3.5.0-9 works correctly and that if the NX RPM is built with that version, this bug doesn't exist.  See the following openSuSE bug:
