Using the 64bit version of vncsnapshot, I get an error code 120 from
the vncserver.  However, simply copying the 32bit version of
vncsnapshot (from one of my systems at is 32bit) and re-running the
command, the snapshot works.  So for now I have simply replaced the
/usr/bin/vncsnapshot with the 32bit version. I'll clean up the install
later to remove the x86_64 version and re-install the i386 version.
Having the actual command to run helped sort it out really quickly.

Thanks!
