RTC 4.0.5 client on SLES 11 crashs for one user accessing help

We 've just setup RTC cleint on a SLES 11 box .  There are only 2 users using this host.  For one user when they try and access the help files RTC coredumps and crashes. for the other user it works fine.

We can;t seem to understand why it works for one user but to the other.

On crashing the user gets the above. On the cmd line 

cm_sit@sitspt01:~/jazz> GConf Error:

to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a
system crash. See http://projects.gnome.org/gconf/ for information. (Details
