ssconvert error
 

I am running RHEL 6.4. I installed gnumeric (# yum install gnumeric). When I tried to change the spread sheet format (# ssconver text.del test1.xls) I got following error: (

GConf Error: Failed to contact configuration server; some possible causes are that you need 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 - 1: Not running within active session)

(ssconvert:40423): GConf-WARNING **: Directory `/apps/gnumeric' was not being monitored by GConfClient 0x2598c00


I google the error but could not get exact solution to get rid of this error message. Any help will be appreciated.
